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

Xin Yin (2):
  ext4: fast commit may not fallback for ineligible commit
  ext4: fast commit may miss file actions
