[PATCH V4 0/3] xen-blkfront/blkback discard support
Dear list,
This is the V4 of the trim support for xen-blkfront/blkback,
Now we move BLKIF_OP_TRIM to BLKIF_OP_DISCARD, and dropped all
"trim" stuffs in the patches, and use "discard" instead.
Also we updated the helpers of blkif_x86_{32|64}_request or we
will meet problems using a non-native protocol.
And this patch has been tested with both SSD and raw file,

With memory pressure, their pages were spread out all of pageblock and
