X-Git-Tag: v3.0-rc1~162^2~19 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=edf6ef59ec7ee82cadc93528229c4097b6c92a7e;p=pandora-kernel.git xen-blkfront: Introduce BLKIF_OP_FLUSH_DISKCACHE support. If the backend supports the 'feature-flush-cache' mode, use that instead of the 'feature-barrier' support. Currently there are three backends that support the 'feature-flush-cache' mode: NetBSD, Solaris and Linux kernel. The 'flush' option is much light-weight version than the 'barrier' support so lets try to use as there are no filesystems in the kernel that use full barriers anymore.
