commit 472c6e46f589c26057596dcba160712a5b3e02c5 upstream.
[partial backport for dependency - xfs_ioc_space() still uses XFS_PREALLOC_SYNC]
Callers can acheive the same thing by calling xfs_log_force_inode() after making their modifications. There is no need for xfs_update_prealloc_flags() to do this.
