[patch 03/35 error-handling] reiserfs: use buffer_info for leaf_paste_entries
From: Jeff Mahoney
Date: Mon Mar 30 2009 - 14:17:07 EST
This patch makes leaf_paste_entries more consistent with respect to the
other leaf operations. Using buffer_info instead of buffer_head directly
allows us to get a superblock pointer for use in error handling.
