From deba0f49b9345f885a53a077623a68cef89c01d5 Mon Sep 17 00:00:00 2001 From: Adrian Bunk Date: Tue, 16 Oct 2007 23:26:03 -0700 Subject: [PATCH] fs/reiserfs/: 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() Signed-off-by: Adrian Bunk Acked-by: Vladimir V.
