From b5be1a1c4c57a092cb60c709a0491d4ecead3d58 Mon Sep 17 00:00:00 2001 From: Sachin Prabhu Date: Mon, 25 Nov 2013 17:09:49 +0000 Subject: cifs: Rename and cleanup open_query_close_cifs_symlink() Rename open_query_close_cifs_symlink to cifs_query_mf_symlink() to make the name more consistent with other protocol version specific functions. We also pass tcon as an argument to the function. This is already available in the calling functions and we can avoid having to make an unnecessary lookup.
