[PATCH] Revert "xen: add helpers to allocate unpopulated memory"

by Marek Marczykowski-Górecki

This reverts commit 9e2369c06c8a181478039258a4598c1ddd2cadfa. On a Xen PV dom0, with NVME disk, this makes the dom0 crash when starting a domain. This looks like some bad interaction between xen-blkback and NVME driver, both using ZONE_DEVICE. Since the author is on leave now, revert the change until proper solution is developed. The specific crash message is: general protection fault, probably for non-canonical address 0xdead000000000100: 0000 [#1] SMP NOPTI CPU: 1 PID: 134 Comm: kworker/u12:2 Not tainted 5.9.9-1.qubes.x86_64 #1 Hardware name: LENOVO 20M9CTO1WW/20M9CTO1WW, BIOS N2CET50W (1.33 ) 01/15/2020 Workqueue: dm-thin do_worker [dm_thin_pool] RIP: e030:nvme_map_data+0x300/0x3a0 [nvme] Code: b8 fe ff ff e9 a8 fe ff ff 4c 8b 56 68 8b 5e 70 8b 76 74 49 8b 02 48 c1 e8 33 83 e0 07 83 f8 04 0f 85 f2 fe ff ff 49 8b 42 08 <83> b8 d0 00 00 00 04 0f 85 e1 fe ff ff e9 38 fd ff ff 8b 55 70 be RSP: e02b:ffffc900010e7ad8 EFLAGS: 00010246 RAX: dead000000000100 RBX: 0000000000001000 RCX: ffff8881a58f5000 RDX: 0000000000001000 RSI: 0000000000000000 RDI: ffff8881a679e000 RBP: ffff8881a5ef4c80 R08: ffff8881a5ef4c80 R09: 0000000000000002 R10: ffffea0003dfff40 R11: 0000000000000008 R12: ffff8881a679e000 R13: ffffc900010e7b20 R14: ffff8881a70b5980 R15: ffff8881a679e000 FS: 0000000000000000(0000) GS:ffff8881b5440000(0000) knlGS:0000000000000000 CS: e030 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000001d64408 CR3: 00000001aa2c0000 CR4: 0000000000050660 Call Trace: nvme_queue_rq+0xa7/0x1a0 [nvme] __blk_mq_try_issue_directly+0x11d/0x1e0 ?

[PATCH 5.10 4/5] io_uring: fix io_cqring_events()'s noflush

by Pavel Begunkov

Checking !list_empty(&ctx->cq_overflow_list) around noflush in io_cqring_events() is racy, because if it fails but a request overflowed just after that, io_cqring_overflow_flush() still will be called. Remove the second check, it shouldn't be a problem for performance, because there is cq_check_overflow bit check just above.

[PATCH 5.10 3/5] io_uring: fix racy IOPOLL flush overflow

by Pavel Begunkov

It's not safe to call io_cqring_overflow_flush() for IOPOLL mode without hodling uring_lock, because it does synchronisation differently. Make sure we have it. As for io_ring_exit_work(), we don't even need it there because io_ring_ctx_wait_and_kill() already set force flag making all overflowed requests to be dropped.
