Hi Linus,
Here are the block changes and update for the 6.17 kernel release. This
pull request contains:
- MD pull request via Yu
- call del_gendisk synchronously, from Xiao
- cleanup unused variable, from John
- cleanup workqueue flags, from Ryo
- fix faulty rdev can't be removed during resync, from Qixing
- NVMe pull request via Christoph
- try PCIe function level reset on init failure (Keith Busch)
- log TLS handshake failures at error level (Maurizio Lombardi)
- pci-epf: do not complete commands twice if nvmet_req_init()
fails (Rick Wertenbroek)
- misc cleanups (Alok Tiwari)
- Removal of the pktcdvd driver. This has been more than a decade coming
at this point, and some recently revealed breakages that had it
causing issues even for cases where it isn't required made me re-pull
the trigger on this one. It's known broken and nobody has stepped up
to maintain the code.
- Series for ublk supporting batch commands, enabling the use of
multishot where appropriate.
- Speed up ublk exit handling.
- Fix for the two-stage elevator fixing which could leak data.
- Convert NVMe to use the new IOVA based API.
- Increase default max transfer size to something more reasonable.
- Series fixing write operations on zoned DM devices.
- Add tracepoints for zoned block device operations.
- Prep series working towards improving blk-mq queue management in the
presence of isolated CPUs.
- Don't allow updating of the block size of a loop device that is
currently under exclusively ownership/open.
- Set chunk sectors from stacked device stripe size and use it for the
atomic write size limit.
- Switch to folios in bcache read_super()
- Fix for CD-ROM MRW exit flush handling.
- Various tweaks, fixes, and cleanups.
Please pull!
