ovl: fix workdir creation
Workdir creation fails in latest kernel. Fix by allowing EOPNOTSUPP as a valid return value from vfs_removexattr(XATTR_NAME_POSIX_ACL_*). Upper filesystem may not support ACL and still be perfectly able to support overlayfs. Reported-by: Martin Ziegler <ziegler@uni-freiburg.de> Signed-off-by: Miklos Szeredi <mszeredi@redhat.com> Fixes: c11b9fdd6a61 ("ovl: remove posix_acl_default from workdir") Cc: <stable@vger.kernel.org>
