Hello, sorry about the delay.

Just one nitpick.

Do we need these two functions?  Can't you either collapse
__simple_xttar_remove() into simple_xattr_remove() or just call
__simple_xattr_remove() directly from simple_xattr_set() with locking
handled there?  Also, why doesn't simple_xattr_remove() have static?

Thanks.
