Subject: [PATCH] xen-blkfront patches for 2.6.40.
Date: Thu, 5 May 2011 14:55:18 -0400 [thread overview]
Message-ID: <1304621721-22608-1-git-send-email-konrad.wilk@oracle.com> (raw)
I am proposing these three patches for 2.6.40.
[PATCH 1/3] xen-blkfront: fix data size for xenbus_gather in blkfront_connect
fixes a bug, while these two:
[PATCH 2/3] xen-blkfront: Provide for 'feature-flush-cache' the BLKIF_OP_WRITE_FLUSH_CACHE operation.
[PATCH 3/3] xen-blkfront: Introduce BLKIF_OP_FLUSH_DISKCACHE support.
Provide the functionality to use the BLKIF_OP_WRITE_FLUSH_CACHE operation, which is
negotiated with the backend if the 'feature-flush-cache' is advertised. Currently there
are three OSes that advertise this flag: NetBSD 5.1 (and unstable), Linux
(devel/xen-blkback-v3.1), and Solaris.
I've tested it with success on NetBSD 5.1 Dom0, and with Linux v2.6.39-rc6 with
the devel/xen-blkback-v3.1 patches.
The git tree with these patches is:
