From: Jeff Mahoney Date: Mon, 30 Mar 2009 18:02:46 +0000 (-0400) Subject: reiserfs: rename p_s_bh to bh X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=ad31a4fc0386e8590c51ca4b8f1ae1d8b8b2ac5e;p=linux-2.6-omap-h63xx.git reiserfs: rename p_s_bh to bh This patch is a simple s/p_s_bh/bh/g to the reiserfs code. This is the second in a series of patches to rip out some of the awful variable naming in reiserfs.
