    Merge tag 'block-6.19-20260109' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux

    Pull block fixes from Jens Axboe:

     - Kill unlikely checks for blk-rq-qos. These checks are really
       all-or-nothing, either the branch is taken all the time, or it's not.
       Depending on the configuration, either one of those cases may be
       true. Just remove the annotation

     - Fix for merging bios with different app tags set

     - Fix for a recently introduced slowdown due to RCU synchronization

     - Fix for a status change on loop while it's in use, and then a later
       fix for that fix

     - Fix for the async partition scanning in ublk
