From: Darrick J. Wong <djwong@xxxxxxxxxx>
At the end of a repair run, xfs_repair clears the superblock's quota
checked flags if it found mistakes in the quota accounting to force a
quotacheck at the next mount. This is currently the last time repair
modifies the primary superblock, so it is sufficient to update the
ondisk buffer and not the incore mount structure.
However, we're about to introduce code to clear the needsrepair feature
at the very end of repair, after all metadata blocks have been written
to disk and all disk caches flush. Since the convention everywhere else
in xfs is to update the incore superblock, call libxfs_sb_to_disk to
translate that into the ondisk buffer, and then write the buffer to
disk, switch the quota CHKD code to use this mechanism too.
