Merge branch 'autopi-deadlock' into for-6.19/block
Currently the automatic block layer PI generation allocates the integrity
buffer using kmalloc, and thus could deadlock, or fail I/O request due
to memory pressure.
Fix this by adding a mempool, and capping the maximum I/O size on PI
capable devices to not exceed the allocation size of the mempool.

* autopi-deadlock:
block: make bio auto-integrity deadlock safe
block: blocking mempool_alloc doesn't fail
