Revision 24a70313969fc3fc440216b40babdb42564acff3 authored by Chris Mason on 21 November 2011, 14:39:11 UTC, committed by Chris Mason on 21 November 2011, 19:57:33 UTC 
Btrfs: remove free-space-cache.c WARN during log replay
 
The log replay code only partially loads block groups, since
the block group caching code is able to detect and deal with
extents the logging code has pinned down.

While the logging code is pinning down block groups, there is
a bogus WARN_ON we're hitting if the code wasn't able to find
an extent in the cache.  This commit removes the warning because
it can happen any time there isn't a valid free space cache
for that block group.
