Pulls in uaf fix for bfqq->bic along with fixups. I pulled in the
backport dependencies that were also present in 5.15-lts.

NeilBrown (1):
  block/bfq-iosched.c: use "false" rather than "BLK_RW_ASYNC"

Yu Kuai (4):
  block, bfq: fix possible uaf for 'bfqq->bic'
  block, bfq: fix uaf for bfqq in bfq_exit_icq_bfqq
  block, bfq: replace 0/1 with false/true in bic apis
  block, bfq: fix uaf for bfqq in bic_set_bfqq()

 block/bfq-cgroup.c  |  8 ++++----
 block/bfq-iosched.c | 19 +++++++++++++------
