This deletes our old lock ordering based deadlock avoidance code.

This is needed by the cycle detector in bcachefs - we need a way to
iterater over waitlist entries while dropping and retaking the waitlist
lock.

With the new method where the thread doing the wakeup after unlock takes
the lock on behalf of the thread waiting for the lock, we don't want to
spin calling trylock() anymore - we can instead spin on
wait->lock_acquired, and not have to touch the lock's cacheline.
Also, osq_lock doesn't make much sense for six locks; multiple readers
may be waiting on a single thread to drop the write lock, and dropping
it simplifies the code a bit more.

This brings back an important optimization, to avoid touching the wait
lists an extra time, while preserving the property that a thread is on a
lock waitlist iff it is waiting - it is never removed from the waitlist
until it has the lock.

This switches to a single list of waiters, instead of separate lists for
read and intent, and switches write locks to also use the wait lists
instead of being handled differently.
Also, removal from the wait list is now done by the process waiting on
the lock, not the process doing the wakeup. This is needed for the new
deadlock cycle detector - we need tasks to stay on the waitlist until
they've successfully acquired the lock.

- Add a flag, has_indent_or_tabstops, that is set if indent level or
tabstops are set.
- Tabstops can no longer be set by modifying the tabstop array
directly: instead, the new functions are provided:
printbuf_tabstop_push() - add a new tabstop, n spaces after
previous tabstop
printbuf_tabtstop_pop() - remove previous tabstop
printbuf_tabstops_reset() - remove all tabstops

The next step in this patch series for improving debugging of shrinker
related issues: keep counts of number of objects we request to free vs.
actually freed, and prints them in shrinker_to_text().
Shrinkers won't necessarily free all objects requested for a variety of
reasons, but if the two counts are wildly different something is likely
amiss.

This adds a new callback method to shrinkers which they can use to
describe anything relevant to memory reclaim about their internal state,
for example object dirtyness.
This uses the new printbufs to output to heap allocated strings, so that
the .to_text() methods can be used both for messages logged to the
console, and also sysfs/debugfs.
This patch also adds shrinkers_to_text(), which reports on the top 10
shrinkers - by object count - in sorted order, to be used in OOM
reporting.

This implements a new %p format string extensions for passing a pretty
printer and its arguments to printk, which will then be inserted into
the formatted output.
A pretty-printer is a function that takes as its first argument a
pointer to a struct printbuf, and then zero or more additional pointer
arguments - these being the objects to format and print.
The arguments to the pretty-printer function are denoted in the format
string by %p, i.e
%pf() foo0_to_text(struct printbuf *out)
%pf(%p) foo1_to_text(struct printbuf *out, struct foo *)
%pf(%p,%p) foo2_to_text(struct printbuf *out, struct foo *)
We'd also like to eventually support non pointer arguments - in
particular, integers - but this will probably require libffi.
Typechecking is accomplished with the CALL_PP macro, which verifies that
the arguments passed to sprintf match the types of the pp-function
arguments, and passes a struct with a cookie to sprintf so that sprintf
can verify that the CALL_PP() macro was used.
Full example:
static void foo_to_text(struct printbuf *out, struct foo *foo)
{
prt_printf(out, "bar=%u baz=%u", foo->bar, foo->baz);
}
printf("%pf(%p)", CALL_PP(foo_to_text, foo));
The goal is to replace most of our %p format extensions with this
interface, and to move pretty-printers out of the core vsprintf.c code -
this will get us better organization and better discoverability (you'll
be able to cscope to pretty printer calls!), as well as eliminate a lot
of dispatch code in vsprintf.c.

This converts the seq_bufs in dynevent_cmd and trace_seq to printbufs.
- read_pos in seq_buf doesn't exist in printbuf, so is added to
trace_seq
- seq_buf_to_user doesn't have a printbuf equivalent, so is inlined
into trace_seq_to_user
- seq_buf_putmem_hex currently swabs bytes on little endian, hardcoded
to 8 byte units. This patch switches it to prt_hex_bytes(), which
does _not_ swab.
Otherwise this is largely a direct conversion, with a few slight
refactorings and cleanups.

This adds options to printbuf for specifying whether units should be
printed raw (default) or with human readable units, and for controlling
whether human-readable units should be base 2 (default), or base 10.
This also adds new helpers that obey these options:
- pr_human_readable_u64
- pr_human_readable_s64
These obey printbuf->si_units
- pr_units_u64
- pr_units_s64
These obey both printbuf-human_readable_units and printbuf->si_units

This patch adds two new features to printbuf for structured formatting:
- Indent level: the indent level, as a number of spaces, may be
increased with pr_indent_add() and decreased with pr_indent_sub().
Subsequent lines, when started with pr_newline() (not "\n", although
that may change) will then be intended according to the current
indent level. This helps with pretty-printers that structure a large
amonut of data across multiple lines and multiple functions.
- Tabstops: Tabstops may be set by assigning to the printbuf->tabstops
array.
Then, pr_tab() may be used to advance to the next tabstop, printing
as many spaces as required - leaving previous output left justified
to the previous tabstop. pr_tab_rjust() advances to the next tabstop
but inserts the spaces just after the previous tabstop - right
justifying the previously-outputted text to the next tabstop.

This makes printbufs optionally heap allocated: a printbuf initialized
with the PRINTBUF initializer will automatically heap allocate and
resize as needed.
Allocations are done with GFP_KERNEL: code should use e.g.
memalloc_nofs_save()/restore() as needed. Since we do not currently have
memalloc_nowait_save()/restore(), in contexts where it is not safe to
block we provide the helpers
printbuf_atomic_inc()
printbuf_atomic_dec()
When the atomic count is nonzero, memory allocations will be done with
GFP_NOWAIT.
On memory allocation failure, output will be truncated. Code that wishes
to check for memory allocation failure (in contexts where we should
return -ENOMEM) should check if printbuf->allocation_failure is set.
Since printbufs are expected to be typically used for log messages and
on a best effort basis, we don't return errors directly.
Other helpers provided by this patch:
- printbuf_make_room(buf, extra)
Reallocates if necessary to make room for @extra bytes (not including
terminating null).
- printbuf_str(buf)
Returns a null terminated string equivalent to the contents of @buf.
If @buf was never allocated (or allocation failed), returns a
constant empty string.
- printbuf_exit(buf)
Releases memory allocated by a printbuf.

This converts most of the hexdump code to printbufs, along with some
significant cleanups and a bit of reorganization. The old non-printbuf
functions are mostly left as wrappers around the new printbuf versions.
Big note: byte swabbing behaviour
Previously, hex_dump_to_buffer() would byteswab the groups of bytes
being printed on little endian machines. This behaviour is... not
standard or typical for a hex dumper, and this behaviour was silently
added/changed without documentation (in 2007).
Given that the hex dumpers are just used for debugging output, nothing
is likely to break, and hopefully by reverting to more standard
behaviour the end result will be _less_ confusion, modulo a few kernel
developers who will certainly be annoyed by their tools changing.

This converts vsnprintf() to printbufs: instead of passing around raw
char * pointers for current buf position and end of buf, we have a real
type!
This makes the calling convention for our existing pretty printers a lot
saner and less error prone, plus printbufs add some new helpers that
make the code smaller and more readable, with a lot less crazy pointer
arithmetic.
There are a lot more refactorings to be done: this patch tries to stick
to just converting the calling conventions, as that needs to be done all
at once in order to avoid introducing a ton of wrappers that will just
be deleted.
Thankfully we have good unit tests for printf, and they have been run
and are all passing with this patch.
We have two new exported functions with this patch:
- prt_printf(), which is like snprintf but outputs to a printbuf
- prt_vprintf, like vsnprintf
These are the actual core print routines now - vsnprintf() is a wrapper
around prt_vprintf().

Like the upcoming vsprintf.c conversion, this converts string_escape_mem

This adds printbufs: a printbuf points to a char * buffer and knows the
size of the output buffer as well as the current output position.
Future patches will be adding more features to printbuf, but initially
printbufs are targeted at refactoring and improving our existing code in
lib/vsprintf.c - so this initial printbuf patch has the features
required for that.

Convert the inode hash table to a RCU-aware hash-bl table just like
the dentry cache. Note that we need to store a pointer to the
hlist_bl_head the inode has been added to in the inode so that when
it comes to unhash the inode we know what list to lock. We need to
do this because the hash value that is used to hash the inode is
generated from the inode itself - filesystems can provide this
themselves so we have to either store the hash or the head pointer
in the inode to be able to find the right list head for removal...

This is needed to fix a page cache coherency issue with O_DIRECT writes.
O_DIRECT writes (and other filesystem operations that modify file data
while bypassing the page cache) need to shoot down ranges of the page
cache - and additionally, need locking to prevent those pages from
pulled back in.
But O_DIRECT writes invoke the page fault handler (via get_user_pages),
and the page fault handler will need to take that same lock - this is a
classic recursive deadlock if userspace has mmaped the file they're DIO
writing to and uses those pages for the buffer to write from, and it's a
lock ordering deadlock in general.
Thus we need a way to signal from the dio code to the page fault handler
when we already are holding the pagecache add lock on an address space -
this patch just adds a member to task_struct for this purpose. For now
only bcachefs is implementing this locking, though it may be moved out
of bcachefs and made available to other filesystems in the future.

The function __ata_change_queue_depth() uses the helper
ata_scsi_find_dev() to get the ata_device structure of a scsi device and
set that device maximum queue depth. However, when the ata device is
managed by libsas, ata_scsi_find_dev() returns NULL, turning
__ata_change_queue_depth() into a nop, which prevents the user from
setting the maximum queue depth of ATA devices used with libsas based
HBAs.
Fix this by renaming __ata_change_queue_depth() to
ata_change_queue_depth() and adding a pointer to the ata_device
structure of the target device as argument. This pointer is provided by
ata_scsi_change_queue_depth() using ata_scsi_find_dev() in the case of
a libata managed device and by sas_change_queue_depth() using
sas_to_ata_dev() in the case of a libsas managed ata device.
