We have a node chain to serialize node block writes, so if any IOs for
node block writes are reordered, we'll get broken node chain. IOWs,
roll-forward recovery will see all or none node blocks given fsync

E.g.,
Node chain consists of:
N1 -> N2 -> N3 -> NFSYNC -> N1' -> N2' -> N'FSYNC

This patch supports to enable f2fs to accept quota information through
mount option:
- {usr,grp,prj}jquota=
- jqfmt=
Then, in ->mount flow, we can recover quota file during log replaying,
by this, journelled quota can be supported.

support for f2fs. The interface is kept consistent with the one
of ext4/xfs.

Commit d618ebaf0aa8 ("f2fs: enable small discard by default") enables
f2fs to issue 4K size discard in real-time discard mode. However, issuing
smaller discard may cost more flash lifetime but release less free
space in storage. Since f2fs has ability of

This patch converts most of the in-kernel filesystems that do writeback
out of the pagecache to report errors using the errseq_t-based
infrastructure that was recently added. This allows them to report
errors once for each open file description.
