From f52e0c11305aa09ed56cad97ffc8f0cdc3d78b5d Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 14 Mar 2011 18:56:51 -0400 Subject: New AT_... flag: AT_EMPTY_PATH For name_to_handle_at(2) we'll want both ...at()-style syscall that would be usable for non-directory descriptors (with empty relative pathname). Introduce new flag (AT_EMPTY_PATH) to deal with that and corresponding LOOKUP_EMPTY; teach user_path_at() and path_init() to deal with the latter.
