2022-05-20bcachefs: Convert to lib/printbuf.cprintbuf_v2Kent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2022-04-17bcachefs: Fix pr_tab_rjust()Kent Overstreet
pr_tab_rjust() was broken and leaving a null somewhere in the output string - this patch fixes it and simplifies it a bit. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2022-04-17bcachefs: Heap allocate printbufsKent Overstreet
This patch changes printbufs dynamically allocate and reallocate a buffer as needed. Stack usage has become a bit of a problem, and a major cause of that has been static size string buffers on the stack. The most involved part of this refactoring is that printbufs must now be exited with printbuf_exit(). Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2022-04-17bcachefs: Convert bch2_pd_controller_print_debug() to a printbufKent Overstreet
Fewer random on-stack char arrays. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2022-04-17bcachefs: Add tabstops to printbufsKent Overstreet
Now, when outputting to printbufs, we can set tabstops and left or right justify text to them - this is to be used by the userspace 'bcachefs fs usage' command. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2022-04-17bcachefs: Add .to_text() methods for all superblock sectionsKent Overstreet
This patch improves the superblock .to_text() methods and adds methods for all types that were missing them. It also improves printbufs by allowing them to specfiy what units we want to be printing in, and adds new wrapper methods for unifying our kernel and userspace environments.

2022-04-17bcachefs: Kill bch_scnmemcpy()Kent Overstreet
bch_scnmemcpy was for printing length-limited strings that might not have a terminating null - turns out sprintf & pr_buf can do this with %.*s. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2022-04-17bcachefs: bch2_hprint(): don't print decimal if conversion was exactKent Overstreet
There's places where we parse these numbers, and our parsing doesn't cope with decimals currently - this is a hack to get the device_add path working again where for the device blocksize there doesn't ever need to be a decimal. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2022-04-17bcachefs: Don't allocate too-big biosKent Overstreet
This fixes a null ptr deref in bio_alloc_bioset() -> biovec_slab() Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2022-04-17bcachefs: Fix a pcpu var splatKent Overstreet
this_cpu_ptr() emits a warning when used without preemption disabled - harmless in this case, as we have other locking where bch2_acc_percpu_u64s() is used. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2022-04-17bcachefs: Don't disable preemption unnecessarilyKent Overstreet
Small improvements to some percpu utility code. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2022-04-17bcachefs: Eliminate more PAGE_SIZE usesKent Overstreet
In userspace, we don't really have a well defined PAGE_SIZE and shouln't be relying on it. This is some more incremental work to remove references to it. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2022-04-17bcachefs: Build fixes for 32bit x86Kent Overstreet
PAGE_SIZE and size_t are not unsigned longs on 32 bit, annoying... also switch to atomic64_cmpxchg instead of cmpxchg() for journal_seq_copy, as atomic64_cmpxchg has a fallback that uses spinlocks for when it's not supported. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2022-04-17bcachefs: Convert various code to printbufKent Overstreet
printbufs know how big the buffer is that was allocated, so we can get rid of the random PAGE_SIZEs all over the place. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2022-04-17bcachefs: Make memcpy_to_bio() param constKent Overstreet

2022-04-17bcachefs: Initial commitKent Overstreet
Forked from drivers/md/bcache, now a full blown COW multi device filesystem with a long list of features - https://bcachefs.org Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
