Kernel devs noted that almost all callers to posix_acl_to_xattr() would check the ACL value size and allocate a buffer before make the call. To reduce the repetition, they've changed it to allocate this buffer internally and return it. Unfortunately that's not true for us; most of our calls are from xattr_handler->get() to convert a stored ACL to an xattr, and that call provides a buffer. For now we have no other option, so this commit detects the new version and wraps to copy the value back into the provided buffer and then free it.
