Subject: [PATCH 8/9] d_path: Make seq_path() use a struct path argument
Date: Mon, 05 Nov 2007 17:32:40 +0100 [thread overview]
Message-ID: <20071105163234.466356640@hasse.suse.de> (raw)
In-Reply-To: 20071105163232.550298985@hasse.suse.de
[-- Attachment #1: vfs/d_path-Make_seq_path_use_a_struct_path_argument.diff --]
[-- Type: text/plain, Size: 6100 bytes --]
seq_path() is always called with a dentry and a vfsmount from a struct
path. Make seq_path() take it directly as an argument.
