This is a flavor of test generic/545 with FS_IOC_FSSETXATTR ioctl instead of FS_IOC_SETFLAGS ioctl. Overlayfs gained support for FS_IOC_FSSETXATTR ioctl in v5.2-rc4 with buggy capability check. This change fixed the problem: ovl: fix wrong flags check in FS_IOC_FS[SG]ETXATTR ioctls Signed-off-by: Amir Goldstein <amir73il@gmail.com> Reviewed-by: Eryu Guan <guaneryu@gmail.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
