Subject: [GIT PULL] Block driver changes for 4.8-rc
Hi Linus,
This builds on top of the core branch I just sent out. This branch also
contains core changes. I've come to the conclusion that from 4.9 and
forward, I'll be doing just a single branch. We often have dependencies
between core and drivers, and it's hard to always split them up
appropriately without pulling core into drivers when that happens.
This branch will also have a few merge conflicts, primarily around the
missing bio_put() that was fixed in -4.7-rc.
That said, this pull request contains:
- Separate secure erase type for the core block layer, from Christoph.
- Set of discard fixes, from Christoph.
- Bio shrinking fixes from Christoph, as a followup up to the op/flags
change in the core branch.
- Map and append request fixes from Christoph.
- NVMeF (NVMe over Fabrics) code from Christoph. This is pretty
exciting!
- nvme-loop fixes from Arnd.
- Removal of ->driverfs_dev from Dan, after providing a
device_add_disk() helper.
- Bcache fixes from Bhaktipriya and Yijing.
- cdrom subchannel read fix from Vchannaiah.
- Set of lightnvm updates from Wenwei, Matias, Johannes, and Javier.
- Set of drbd updates and fixes from Fabian, Lars, and Philipp.
- mg_disk error path fix from Bart.
- User notification for failed device add for loop, from Minfei.
- NVMe in general:
- NVMe delay quirk from Guilherme.
- SR-IOV support and command retry limits from Keith.
- Fix for memory-less NUMA node from Masayoshi.
- Use UINT_MAX for discard sectors, from Minfei.
- Cancel IO fixes from Ming.
- Don't allocate unused major, from Neil.
- Error code fixup from Dan.
- Use constants for PSDT/FUSE from James.
- Variable init fix from Jay.
- Fabrics fixes from Ming, Sagi, and Wei.
- Various fixes.
Please pull!
