xfs: force the log after remapping a synchronous-writes file
[ Upstream commit 5ffce3c ] Commit 5833112 tried to make it so that a remap operation would force the log out to disk if the filesystem is mounted with mandatory synchronous writes. Unfortunately, that commit failed to handle the case where the inode or the file descriptor require mandatory synchronous writes. Refactor the check into into a helper that will look for all three conditions, and now we can treat reflink just like any other synchronous write. Fixes: 5833112 ("xfs: reflink should force the log out if mounted with wsync") Signed-off-by: Darrick J.
