Hi Linus, Here are the main block updates for the 6.3 merge window. Note that this will throw a trivial merge conflict due to a late fix for BFQ in the 6.2 release, both are trivial to resolve and just in case there are questions, I've pushed a merged branch here: https://git.kernel.dk/cgit/linux-block/log/?h=for-6.3/block-merged which resolves those two as-of your git tree today. This pull request contains: - NVMe updates via Christoph: - Small improvements to the logging functionality (Amit Engel) - Authentication cleanups (Hannes Reinecke) - Cleanup and optimize the DMA mapping cod in the PCIe driver (Keith Busch) - Work around the command effects for Format NVM (Keith Busch) - Misc cleanups (Keith Busch, Christoph Hellwig) - Fix and cleanup freeing single sgl (Keith Busch) - MD updates via Song: - Fix a rare crash during the takeover process - Don't update recovery_cp when curr_resync is ACTIVE - Free writes_pending in md_stop - Change active_io to percpu - Series updating drbd, inching us closer to unifying the out-of-tree driver with the in-tree one (Andreas, Christoph, Lars, Robert) - BFQ update adding support for multi-actuator drives (Paolo, Federico, Davide) - Make brd compliant with REQ_NOWAIT (me) - Fix for IOPOLL and queue entering, fixing stalled IO waiting on timeouts (me) - Fix for REQ_NOWAIT with multiple bios (me) - Fix memory leak in blktrace cleanup (Greg) - Series cleaning up sbitmap and fixing a potential hang (Kemeng) - Series cleaning up some bits in BFQ, and fixing a bug in the request injection (Kemeng) - Series cleaning up the request allocation and issue code, and fixing some bugs related to that (Kemeng) - ublk updates and fixes: - Add support for unprivileged ublk (Ming) - Improve device deletion handling (Ming) - Misc (Liu, Ziyang) - s390 dasd fixes (Alexander, Qiheng) - Improve utility of request caching and fixes (Anuj, Xiao) - zoned cleanups (Pankaj) - More constification for kobjs (Thomas) - blk-iocost cleanups (Yu) - Remove bio splitting from drivers that don't need it (Christoph) - Series switching blk-cgroups using struct gendisk. Some of this is now incomplete as select late reverts were done. (Christoph) - Series adding bvec initialization helpers, and converting callers to use that rather than open-coding it (Christoph) - Misc fixes and cleanups (Jinke, Keith, Arnd, Bart, Li, Martin, Matthew, Ulf, Zhong) Please pull!
