From: Christoph Hellwig Date: Fri, 3 Apr 2020 18:45:37 +0000 (-0700) Subject: xfs: reflink should force the log out if mounted with wsync X-Git-Tag: v5.7-rc1~29^2 X-Git-Url: https://repo.jachan.dev/linux.git/commitdiff_plain/5833112df7e9 xfs: reflink should force the log out if mounted with wsync Reflink should force the log out to disk if the filesystem was mounted with wsync, the same as most other operations in xfs. [Note: XFS_MOUNT_WSYNC is set when the admin mounts the filesystem with either the 'wsync' or 'sync' mount options, which effectively means that we're classifying reflink/dedupe as IO operations and making them synchronous when required.] Fixes: 3fc9f5e409319 ("xfs: remove xfs_reflink_remap_range") Signed-off-by: Christoph Hellwig Reviewed-by: Brian Foster [darrick: add more to the changelog] Reviewed-by: Darrick J.
