From 1414a6046ab402ac21545522270c32c576327eb9 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 20 Apr 2010 17:02:50 +1000 Subject: [PATCH] xfs: remove dead XFS_LOUD_RECOVERY code This can't be enabled through the build system and has been dead for ages. Note that the CRC patches add back log checksumming, but the code is quite different from the version removed here anyway.
