From 79df1baeec29022e4181f2964187b88661ef5517 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Mon, 6 Dec 2010 12:52:08 -0500 Subject: cifs: fix use of CONFIG_CIFS_ACL Some of the code under CONFIG_CIFS_ACL is dependent upon code under CONFIG_CIFS_EXPERIMENTAL, but the Kconfig options don't reflect that dependency. Move more of the ACL code out from under CONFIG_CIFS_EXPERIMENTAL and under CONFIG_CIFS_ACL. Also move find_readable_file out from other any sort of Kconfig option and make it a function normally compiled in.

In that case, it's likely that the master_tlink pointer has not yet been instantiated. Fix this by having cifs_build_path_to_root take a cifsTconInfo pointer as well, and have the caller pass that in.
