From 850265335f792f5d39ab24e5fb7160bac28d77e5 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Tue, 15 Mar 2011 14:52:12 -0400 Subject: Btrfs: return error if the range we want to map is bogus Currently if we have corrupt metadata map_extent_buffer will complain about it, but not return an error so the caller has no idea a problem was hit. Fix this.
