Subject: [GIT PULL] barrier/flush write revamp for 2.6.37-rc1
Date: Fri, 22 Oct 2010 12:39:02 +0200 [thread overview]
Message-ID: <4CC169C6.6030104@fusionio.com> (raw)
Hi Linus,
Another topic branch, this one has the barrier rewrite for 2.6.37-rc1.
It's been in for-next for a long time, no surprises seen yet (except for
the xen-blkfront, but that was broken before as well).
This greatly simplifies the barrier support and semantics, as the
diffstat confirms.
Please pull.
