[PATCH 0/8] Restriper fixes

[Ilya Dryomov <idryomov@gmail.com>]

Hi Chris,

The main one here is the improvement to btrfs_can_relocate(), which is
now a tiny bit smarter and does not return ENOSPC when there's plenty of
unallocated space for target chunks.  This, in addition to my patch
which disables silent profile "upgrades", should lower a number of
corner cases in profile changing.

The rest are a bunch of cleanups and some minor fixes.

Thanks,
