In keeping with the notion that all tools should be simple for
all to use. I've changed ktest.pl to ask for mandatory options
instead of just failing. It will append (or create) the options
the user types in, onto the config file.

During the config_bisect, in case of failure, it is nice to have
the last good and bad .configs that were used. This would let
us restart the config_bisect from those configs.
Copy the last good config into the output dir as config_good,
and the last bad config as config_bad.

Added the options STOP_AFTER_SUCCESS and STOP_AFTER_FAILURE to
allow the user to give a time (in seconds) to stop the monitor
after a stack trace or login has been detected. Sometimes the
kernel constantly prints out to the console and this may cause
the test to run indefinitely.

When we store failures, we create a directory that has the build_type
in it. For useconfig, it also contains the name path of the config
file it uses. This unfortunately gets its own directory on failure.
Parse off the directory name when creating the directory to store
the failures.

Added the ability to do a config_bisect. It starts with a bad
config and does the following loop.
Enable half the configs.
if none of the configs to check are not enabled
(caused by missing dependencies) enable the other half.
Run the test
if the test passes, remove the configs from the check
but enabled them for further tests (to satisfy
dependencies).
else
Remove any config that was not enabled, as we have found
a new config that can cause a failure.

Change the config to use TEST_START where the options after a
TEST_START automatically get the [] as it is read and they do
not need to exist in the config file;
TEST_START
MIN_CONFIG = myconfig
is the same as
MIN_CONFIG[1] = myconfig
The benefit is that you no longer need to keep track of test numbers
with tests.
Also process the commit ids that are passed to the options
to get the actually SHA1 so it is no longer relative to the branch.
Ie, saying HEAD will get the current SHA1 and then that will
be used, and will work even if another branch is checked out.

It is much better to keep the monitor running throughout a

will show everything that has happened before when opening the

As pointed out by Linus, commit dab5855 ("perf_counter: Add mmap event hooks to
mprotect()") is fundamentally wrong as mprotect_fixup() can free 'vma' due to
merging. Fix the problem by moving perf_event_mmap() hook to
mprotect_fixup().
Note: there's another successful return path from mprotect_fixup() if old
flags equal to new flags. We don't, however, need to call
perf_event_mmap() there because 'perf' already knows the VMA is
executable.

Commit 13cfb7334e made cifs_ioctl use the tlink attached to the
cifsFileInfo for a filp. This ignores the case of an open directory
however, which in CIFS can have a NULL private_data until a readdir
is done on it.
This patch re-adds the NULL pointer checks that were removed in commit
50ae28f01 and moves the setting of tcon and "caps" variables lower.
Long term, a better fix would be to establish a f_op->open routine for
directories that populates that field at open time, but that requires
some other changes to how readdir calls are handled.

Commit 5c521830cf (ext4: Support discard requests when running in
no-journal mode) attempts to add sb_issue_discard() for data blocks
(in data=writeback mode) and in no-journal mode. Unfortunately, this
no longer works, because in commit dd3932eddf (block: remove
BLKDEV_IFL_WAIT), sb_issue_discard() only presents a synchronous
interface, and there are times when we call ext4_free_blocks() when we
are are holding a spinlock, or are otherwise in an atomic context.
For now, I've removed the call to sb_issue_discard() to prevent a
deadlock or (if spinlock debugging is enabled) failures like this:

The following BUG can occur when an inode which is getting freed when
it still has dirty pages outstanding, and it gets deleted (in this
because it was the target of a rename). In ordered mode, we need to
make sure the data pages are written just in case we crash before the
rename (or unlink) is committed. If the inode is being freed then
when we try to igrab the inode, we end up tripping the BUG_ON at
fs/ext4/page-io.c:146.
To solve this problem, we need to keep track of the number of io
callbacks which are pending, and avoid destroying the inode until they
have all been completed. That way we don't have to bump the inode
count to keep the inode from being destroyed; an approach which
doesn't work because the count could have already been dropped down to
zero before the inode writeback has started (at which point we're not
allowed to bump the count back up to 1, since it's already started
getting freed).
Thanks to Dave Chinner for suggesting this approach, which is also
used by XFS.
