The disadvantage of it would be the additional call for file-has-acl() so hence few more kernel calls.
Can the extra syscalls be avoided by migrating/copying some of file-has-acl.c's functionality into qcopy-acl.c? The idea would be to invoke listxattr just once in the usual case, to handle both file_has_acl checking and qcopy_acl copying.
