Subject: [GIT PULL] Block IO core changes for 3.10
Hi Linus,
Below are the block layer core changes for 3.10. The pull request
contains:
- Major bit is Kents prep work for immutable bio vecs.
- Stable candidate fix for a scheduling-while-atomic in the queue bypass
operation.
- Fix for the hang on exceeded rq->datalen 32-bit unsigned when merging
discard bios.
- Tejuns changes to convert the writeback thread pool to the generic
workqueue mechanism.
- Runtime PM framework, SCSI patches exists on top of these in James'
tree.
- A few random fixes.
Please pull! Should satisfy your merge cravings too.
