Test that calling fsync against a file using the merged directory does not result in a crash nor fails unexpectedly. This is motivated by a change in overlayfs that resulted in a crash (invalid memory access) when the lower or upper directory belonged to a btrfs file system. The overlayfs change came in commit 4bacc9c9234 (overlayfs: Make f_path always point to the overlay and f_inode to the underlay). At the moment there are two patches in the linux-fsdevel and linux-btrfs mailing lists to fix this problem: * vfs: add file_dentry() * Btrfs: fix crash/invalid memory access on fsync when using overlayfs Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
