io_uring fixes for 7.3-stable

Hi Greg,

Here are io_uring fixes for 7.3-stable.

They apply on top of v7.3.1 with the current queue-7.3 applied (stable-queue 6575ff04f2fd). They depend on the io_uring patches that are already in queue-7.3: from patch 14 onwards they won't apply to v7.3.1 alone.

The other io_uring fixes I had for 7.3 that are already in queue-7.3 aren't included here.

Cheng Yongkang (2):
io_uring/timeout: count cancelled timeouts in cq_timeouts io_uring/net: fix multishot recv length limit accounting

Chris Mason (6):
io_uring/rsrc: charge buffer arrays and nodes to memcg
io_uring: charge tctx nodes and personalities
io_uring: free XArray nodes left by a failed store io_uring/bpf-ops: clear bpf_ctx while submitting SQEs
io_uring: free the task context after a grace period io_uring/sqpoll: don't wait for the thread to exit

Daan De Meyer (1):
io_uring/net: don't retry a non-blocking connect() that fails with
-EAGAIN

Dominik Maier (2):
io_uring/net: mask socket type with SOCK_TYPE_MASK in
io_socket_bpf_populate()
io_uring/register: enforce per-task restrictions in
io_uring_register_blind()

Jens Axboe (1):
io_uring: keep the drain active when a deferred drain request is
started

Josef Bacik (1):
io_uring/io-wq: no new workers once the exit has begun

Kyle Zeng (1):
io_uring: defer foreign io-wq enqueues to task_work

Yichong Chen (2):
io_uring/kbuf: advance head when a pickup empties the buffer ring io_uring/net: keep recvmsg buffer select length within MAX_RW_COUNT
