Eryu, This is the 3rd revision of crash consistency patch set. I addressed all your review commennts on v2 patches. These patches are originally from Josef Bacik. I've added some debugging options for running fsx and replay-log, which I used to analyze the crash consistency bugs uncovered by the tests. The original fsx crash consistency test (500) is failing sometimes on kernel v4.13 for ext4, btrfs and xfs. A fix for xfs is queued for v4.14, I think there is a fix by Josef for btrfs queued for v4.14 as well. A 'quick' and reliable regression test (501) was created for the ext4 issue. I created another crash consistency test which runs fsx on cloned files (502). This test is failing check fs sometimes on kernel v4.13, at the end of the test, but this is not related to crash consistency. There is a fix is the works for v4.14. A 'quick' and reliable regression test (503) was created for this issue. The new 'clones crash' test (502) is also failing sometimes on xfs_repair errors like: "fatal error -- illegal state 13 in block map 147", on crash points, but I havn't been able to narrow down the issue yet.
