Subject: reiserfs: xattr reiserfs_get_page takes offset instead of index
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=ec6ea56b2f1d3811815e53131e85fd1fc9b51873;p=linux-2.6-omap-h63xx.git

reiserfs: xattr reiserfs_get_page takes offset instead of index

This patch changes reiserfs_get_page to take an offset rather than an
index since no callers calculate the index differently.
