Symlinks cannot have ACLs, so set_acl should either never be defined for symlinks (and a NULL check is then needed in posix_acl_xattr_set()), or it is defined in all inode operations, and S_ISNLNK() check is needed in posix_acl_xattr_set().  That latter check should probably be added in any case to be on the safe side.

Yes, we should add the check.  We also in general should not have
set_acl/get_acl on links and I'll look over it.

Thanks for the review!
