Filesystems can call sb_issue_discard on a memory reclaim path
(e.g. ext4 calls sb_issue_discard during journal commit).

Use GFP_NOFS in sb_issue_discard to avoid recursing back into the FS.

Hi Jens,

I never saw an ack from you on this patch.  Are you ok with it, and
have you grabbed it for your tree?  Do you want me to include this in
the ext4 tree, even though it's a patch to include/linux/blkdev.h?

Hi Ted,

Thanks for following up on this.  In my experience, Jens is more apt to
pick up a patch if it gets explicitly 'Acked-by' other stake-holders
(especially when a patch is motivated by another subsystem, in this case
the proposed block change addresses a problem unique to fs/ext4).

I'll pick this up. I've been away for a few weeks and I'm currently
on vacation, but I'll push this with a few other pending patches
for .35 on monday.
