[PATCH V2 0/5] ublk: NUMA-aware memory allocation

[Ming Lei <ming.lei@redhat.com>]

Hi Jens,

The 1st two patches implement ublk driver NUMA aware memory allocation.

The last two patches implement it for ublk selftest utility.

`taskset -c 0-31 ~/git/fio/t/io_uring -p0 -n16 -r 40 /dev/ublkb0` shows
5%~10% IOPS improvement on one AMD zen4 dual socket machine when creating
ublk/null with 16 queues and AUTO_BUF_REG(zero copy).


V2:
	- use a flexible array member for queues field, save one indirection
	  for retrieving ublk queue
	- rename __queues into queues 
	- remove the queue_size field from struct ublk_device
	- Move queue allocation and deallocation into ublk_init_queue() and
	ublk_deinit_queue() 
	- use flexible array for ublk_queue.ios
	- convert ublk_thread_set_sched_affinity() to use pthread_setaffinity_np()

Ming Lei (5):
  ublk: reorder tag_set initialization before queue allocation
  ublk: implement NUMA-aware memory allocation
  ublk: use flexible array for ublk_queue.ios
  selftests: ublk: set CPU affinity before thread initialization
  selftests: ublk: make ublk_thread thread-local variable
