Date: Fri, 15 Jun 2007 00:16:28 +0200
From: Adrian Bunk <bunk@...sta.de>
To: Andrew Morton <akpm@...ux-foundation.org>,
Vladimir Saveliev <vs@...esys.com>,
Nick Piggin <npiggin@...e.de>
Cc: linux-kernel@...r.kernel.org, reiserfs-dev@...esys.com
Subject: [-mm patch] fs/reiserfs/: cleanups
This patch contains the following cleanups:
- remove the following no longer used functions:
- bitmap.c: reiserfs_claim_blocks_to_be_allocated()
- bitmap.c: reiserfs_release_claimed_blocks()
- bitmap.c: reiserfs_can_fit_pages()
- make the following functions static:
- inode.c: restart_transaction()
- journal.c: reiserfs_async_progress_wait()
