From ea96571f7b865edaf1acd472e6f2cddc9fb67892 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Fri, 5 Apr 2013 14:46:01 -0500 Subject: [PATCH] libceph: fix possible CONFIG_BLOCK build problem This patch: 15a0d7b libceph: record message data length did not enclose some bio-specific code inside CONFIG_BLOCK as it should have. Fix that.
