[PATCH v3 0/2] ext4: fix issues when fast commit work with jbd
From: Xin Yin
Date: Mon Jan 17 2022 - 04:37:20 EST
When test fast commit with xfstests generic/455, some logic issues were
found. When a full commit is ongonig, the logic of fast commit tracking seems
not correct. The first patch fix the ineligible commit case , and the
second patch fix the common fast commit case.
After testing this patch set with xfstests log and quick group, no
regressions were found, and the generic/455 can pass now.

v2: drop EXT4_MF_FC_COMMITTING
v3: change logic of ext4_fc_mark_ineligible() when set 'handle' as NULL.
Fix use-after-free issue for improper use of 'handle' for
ext4_fc_mark_ineligible().
Xin Yin (2):
ext4: fast commit may not fallback for ineligible commit
ext4: fast commit may miss file actions
