From ad31a4fc0386e8590c51ca4b8f1ae1d8b8b2ac5e Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Mon, 30 Mar 2009 14:02:46 -0400 Subject: 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.
