Check if SGID is cleared upon chmod / setfacl when the owner is not in the owning group. As of today, the kernel fails to clear SGID in setxattr (which is what acl_set_file is implemented on top of) in that case; see this patch: https://patchwork.kernel.org/patch/9290507/ Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com> Cc: Jan Kara <jack@suse.cz> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com>
