Re: [PATCH 2/6] Fedora 18 - build-fixes.patch

[Gene Czarcinski <gene@czarc.net>]

I believe that this if the likely source of this patch:
http://article.gmane.org/gmane.comp.file-systems.btrfs/4547

I do wonder how much this is still applicable.  However, it has been in 
the btrfs-progs package for Fedora 15, 16, 17, and 18 plus likely some 
versions of RHEL.
