Hi Linus,
Please find below a set of block related fixes for the 3.6 rc series. It
contains:
- Improvements to the buffered and direct write IO plugging from
Fengguang.
- Abstract out the mapping of a bio in a request, and use that to
provide a blk_bio_map_sg() helper. Useful for mapping just a bio
instead of a full request.
- Regression fix from Hugh, fixing up a patch that went into the
previous release cycle (and marked stable, too) attempting to
prevent a loop in __getblk_slow().
- Updates to discard requests, fixing up the sizing and how we align
them. Also a change to disallow merging of discard requests, since
that doesn't really work properly yet.
- A few drbd fixes.
- Documentation updates.
Please pull!
