[PATCH] xen-blk[front|back] FUA additions.

Is it possible for the ext4/btrfs file system to pass some context related info to low level block driver?
Currently, some new storage devices have the ability to do performance optimizations according to the type of data payload - say, file system metadata, time-stamps, sequential write in some granularity, random write and so on.
For example, the latest eMMC 4.5 device can support the so-called ''Context Management'' and ''Data Tag Mechanism'' features. By receiving
