Subject[PATCH v4 00/24] Prep work for immutable bio vecs
Date
Since last time - split bio integrity stuff out into its own 2 patch series.

Also changed bio_advance() a bit - it now explicitly special cases discard and
WRITE_SAME requests, so that partial completions will work. Previously, partial
completions worked for other requests but would've silently blown up for those
- this'll be of use later too, for generic bio splitting.

I've got 3 patch series queued up but they all should be independent - git tree
is at

http://evilpiepirate.org/git/linux-bcache.git for-jens

It's on top of jens' for-next branch.
