Message-ID: <1373288607-1876-1-git-send-email-roger.pau@citrix.com> Date: Mon, 8 Jul 2013 15:03:23 +0200 From: Roger Pau Monne <roger.pau@...rix.com> To: <xen-devel@...ts.xen.org>, <linux-kernel@...r.kernel.org> Subject: [PATCH RFC 0/4] xen-block: prevent blkfront for hoarding grants The following patches prevent blkfront from hoarding all grants in the system by allowing blkfront to request blkback to unmap certain grants so they can be freed by blkfront. This is done periodically by blkfront, unmapping a certain amount of unused persistent grants. This series also includes a bug fix for the grant table free callback implementation. According to my tests, this series don't introduce any performance regressions, results can be seen at: http://xenbits.xen.org/people/royger/persistent_unmap/ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
