Hi Josh,

The patch is already in the gfs2 "nmw" tree upstream but it hasn't been
pulled by Linus yet:

http://git.kernel.org/cgit/linux/kernel/git/steve/gfs2-3.0-nmw.git/commit/fs/gfs2?id=19aeb5a65f1a6504fc665466c188241e7393d66f

It is not Fedora specific. Maybe I need to send it elsewhere?
I just want to make sure it gets into the Fedora-20 stable kernel and such.
I've always just posted patches like this upstream and let $MAGIC get
them into Fedora, but in this case, the bug is pretty nasty.
