[ Upstream commit 9d5c8190683a462dbc787658467a0da17011ea5f ] [ 27.629441] BUG: sleeping function called from invalid context at fs/file.c:402 [ 27.631317] in_atomic(): 1, irqs_disabled(): 1, non_block: 0, pid: 1012, name: io_wqe_worker-0 [ 27.633220] 1 lock held by io_wqe_worker-0/1012: [ 27.634286] #0: ffff888105e26c98 (&ctx->completion_lock) {....}-{2:2}, at: __io_req_complete.part.102+0x30/0x70 [ 27.649249] Call Trace: [ 27.649874] dump_stack+0xac/0xe3 [ 27.650666] ___might_sleep+0x284/0x2c0 [ 27.651566] put_files_struct+0xb8/0x120 [ 27.652481] __io_clean_op+0x10c/0x2a0 [ 27.653362] __io_cqring_fill_event+0x2c1/0x350 [ 27.654399] __io_req_complete.part.102+0x41/0x70 [ 27.655464] io_openat2+0x151/0x300 [ 27.656297] io_issue_sqe+0x6c/0x14e0 [ 27.660991] io_wq_submit_work+0x7f/0x240 [ 27.662890] io_worker_handle_work+0x501/0x8a0 [ 27.664836] io_wqe_worker+0x158/0x520 [ 27.667726] kthread+0x134/0x180 [ 27.669641] ret_from_fork+0x1f/0x30 Instead of cleaning files on overflow, return back overflow cancellation into io_uring_cancel_files(). Previously it was racy to clean REQ_F_OVERFLOW flag, but we got rid of it, and can do it through repetitive attempts targeting all matching requests.
