Subject: [PATCH RFC 0/4] xen-block: prevent blkfront for hoarding grants
Date: Mon, 8 Jul 2013 15:03:23 +0200 [thread overview]
Message-ID: <1373288607-1876-1-git-send-email-roger.pau@citrix.com> (raw)
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:
