Theodore Ts'o 8fdd60f2ae Revert "ext4: use ext4_write_inode() when fsyncing w/o a journal" ... This reverts commit ad211f3e94. As Jan Kara pointed out, this change was unsafe since it means we lose the call to sync_mapping_buffers() in the nojournal case. The original point of the commit was avoid taking the inode mutex (since it causes a lockdep warning in generic/113); but we need the mutex in order to call sync_mapping_buffers(). The real fix to this problem was discussed here: https://lore.kernel.org/lkml/20181025150540.259281-4-bvanassche@acm.org The proposed patch was to fix a syzbot complaint, but the problem can also demonstrated via "kvm-xfstests -c nojournal generic/113". Multiple solutions were discused in the e-mail thread, but none have landed in the kernel as of this writing. Anyway, commit ad211f3e94 is absolutely the wrong way to suppress the lockdep, so revert it.
