| |
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.
