Message-ID: <20070412162804.GA7240@c2.user-mode-linux.org>
Date: Thu, 12 Apr 2007 12:28:04 -0400
From: Jeff Dike <jdike@...toit.com>
To: Andrew Morton <akpm@...l.org>

Subject: [ PATCH 3/6 ] UML - Rename os_{read_write}_file_k back to os_{read_write}_file
Rename os_{read_write}_file_k back to os_{read_write}_file, delete
the originals and their bogus infrastructure, and fix all the callers.
