Cover letter [0/4] DST: Distributed storage.

Distributed storage.

I'm pleased to announce the 10'th release of the distributed storage subsystem (DST). This is a maintenance release and includes bug fixes and simple feature extensions only.

DST allows to form a storage on top of local and remote nodes and combine them into linear or mirroring setup, which in turn can be exported to remote nodes.

Short changelog:
* fixed bug with XFS metadata update (it can provide slab pages to the

	DST, so it is not allowed to transfer them using ->sendpage())

* fixed async error completion path
* extended netlink communication channel to report errors back to userspace
* DST name is now "The 10'th dynasty of smuggled slothes"
* number of fixes for userspace DST target

Great thanks to Matthew Hodgson <[email protected]> for debugging and fixes for userspace DST target and preliminary netlink extension patches.

Overall list of features of the DST can be found on project's homepage:

Thank you.
