Many tests use dm_flakey to trigger log replay, but for filesystems that don't support metadata journaling, this causes failures when it shouldn't. (i.e. we can hardly test log replay if there is no log, and the subsequent filesystem check will turn up errors). For some tests they actually sync everything we care about, and find inconsistencies elsewhere, but I erred on the side of simply not running the test in most cases.

# FS QA Test No. 311

#
|
|
# Run various fsync tests with dm flakey in freeze() mode and non freeze()
|
|
# mode. The idea is that we do random writes and randomly fsync and verify that
|
|
# after a fsync() followed by a freeze()+failure or just failure that the file
|
|
# is correct. We remount the file system after the failure so that the file
|
|
# system can do whatever cleanup it needs to and md5sum the file to make sure
|
|
# it matches hat it was before the failure. We also fsck to make sure the file
|
|
# system is consistent.
|
|
#
|
|
# The fsync tester just random writes into prealloc or not, and then fsync()s
|
|
# randomly or sync()'s randomly and then fsync()'s before exit. There are a few
|
|
# tests that were handcrafted to reproduce bugs in btrfs, so it's also a
|
|
# regression test of sorts.
