Linux 6.1-rc1

There were two required changes:

  - KUnit moved the assert format function pointer from
    the assertion struct to the kunit_do_failed_assertion()
    call instead.

    See commit a8495ad ("kunit: remove format func from
    struct kunit_assert, get it to 0 bytes").

  - `file_operations` gained the `uring_cmd_iopoll` field.

    See commit de27e18 ("fs: add
    file_operations->uring_cmd_iopoll").
