[GIT,PULL] Block updates for 6.14-rc1

Hi Linus, Here are the block related updates for the 6.14 merge window. This pull request contains: - NVMe pull requests via Keith - Target support for PCI-Endpoint transport (Damien) - TCP IO queue spreading fixes (Sagi, Chaitanya) - Target handling for "limited retry" flags (Guixen) - Poll type fix (Yongsoo) - Xarray storage error handling (Keisuke) - Host memory buffer free size fix on error (Francis) - MD pull requests via Song - Reintroduce md-linear, by Yu Kuai - md-bitmap refactor and fix, by Yu Kuai - Replace kmap_atomic with kmap_local_page, by David Reaver - Quite a few queue freeze and debugfs deadlock fixes. Ming introduced lockdep support for this in the 6.13 kernel, and it's (unsurprisingly) uncovered quite a few issues - Use const attributes for IO schedulers - Remove bio ioprio wrappers - Fixes for stacked device atomic write support - Refactor queue affinity helpers, in preparation for better supporting isolated CPUs - Cleanups of loop O_DIRECT handling - Cleanup of BLK_MQ_F_* flags - Add rotational support for null_blk - Various fixes and cleanups This will throw a trivial conflict in drivers/md/dm-verity-fec.c due to the bio ioprio wrapper removal. The merge is simple, just replace bio_prio(bio) with bio->bi_ioprio in both cases. Please pull! The following changes since commit 4bbf9020becbfd8fc2c3da790855b7042fad455b: Linux 6.13-rc4 (2024-12-22 13:22:21 -0800) are available in the Git repository at: git://git.kernel.dk/linux.git
