Subject: [PATCH 0/3] btrfs: rst: updates for RAID stripe tree

Three independent updates for RAID stripe tree.
The 1st one removes pointless space from the on-disk format. As the
feature itself is still experimental I'd like to get rid of that as early
as possible.

Patch 2 replaces stripe extents in case we hit a EEXIST when inserting a
stripe extent on a write. This can happen i.e. on device-replace.

Patch 3 splits a stripe extent on partial delete of a stripe.
