This time +AD4 it happens to coincide with that is a holiday for most. My plan is to +AD4 send in an EARLY pull request to Linus, Thursday at the latest. If you're +AD4 sitting on anything that should go in with the initial merge, then I need +AD4 to have it ASAP. +AD4 +AD4 I'll do a later pull about a week in with things that were missed, but +AD4 I'm really hoping to make that fixes only. Any driver updates etc should +AD4 go in now. Hi Jens, If I run blktests/srp/002 against Linus' master branch then that test passes, no matter how many times I run that test. If I run that test against your for-next branch however (commit 6a252f2772c0) then that test hangs. The output of my list-pending-block-requests script is as follows when the hang occurs: dm-0 dm-1 dm-1/hctx0/active:0 dm-1/hctx0/flags:alloc+AF8-policy+AD0-FIFO SHOULD+AF8-MERGE+AHw-SG+AF8-MERGE dm-1/hctx0/tags:nr+AF8-tags+AD0-2048 dm-1/hctx0/tags:nr+AF8-reserved+AF8-tags+AD0-0 dm-1/hctx0/tags:active+AF8-queues+AD0-0 dm-1/hctx0/tags:bitmap+AF8-tags: dm-1/hctx0/tags:depth+AD0-2048 dm-1/hctx0/tags:busy+AD0-798 dm-1/hctx0/tags:cleared+AD0-935 dm-1/hctx0/tags:bits+AF8-per+AF8-word+AD0-64 dm-1/hctx0/tags:map+AF8-nr+AD0-32 dm-1/hctx0/tags:alloc+AF8-hint+AD0Aew-682, 463, 595, 1923, 841, 628+AH0 dm-1/hctx0/tags:wake+AF8-batch+AD0-8 dm-1/hctx0/tags:wake+AF8-index+AD0-0 dm-1/hctx0/tags:ws+AF8-active+AD0-0 dm-1/hctx0/tags:ws+AD0Aew dm-1/hctx0/tags: +AHs.wait+AF8-cnt+AD0-8, .wait+AD0-inactive+AH0, dm-1/hctx0/tags: +AHs.wait+AF8-cnt+AD0-8, .wait+AD0-inactive+AH0, dm-1/hctx0/tags: +AHs.wait+AF8-cnt+AD0-8, .wait+AD0-inactive+AH0, dm-1/hctx0/tags: +AHs.wait+AF8-cnt+AD0-8, .wait+AD0-inactive+AH0, dm-1/hctx0/tags: +AHs.wait+AF8-cnt+AD0-8, .wait+AD0-inactive+AH0, dm-1/hctx0/tags: +AHs.wait+AF8-cnt+AD0-8, .wait+AD0-inactive+AH0, dm-1/hctx0/tags: +AHs.wait+AF8-cnt+AD0-8, .wait+AD0-inactive+AH0, dm-1/hctx0/tags: +AHs.wait+AF8-cnt+AD0-8, .wait+AD0-inactive+AH0, dm-1/hctx0/tags:+AH0 dm-1/hctx0/tags:round+AF8-robin+AD0-0 dm-1/hctx0/tags:min+AF8-shallow+AF8-depth+AD0-4294967295 dm-1/hctx0/tags+AF8-bitmap:00000000: ff03 feff ffff ffff ffff ffff ffff ffff dm-1/hctx0/tags+AF8-bitmap:00000010: ffff ffff ffff ffff ffff 1f70 0040 0100 dm-1/hctx0/tags+AF8-bitmap:00000020: ffff ffef f7bf ffe7 ffff ffff ffff ffdf dm-1/hctx0/tags+AF8-bitmap:00000030: ffff ffff ffff ffff ffff ffff ffff ffff dm-1/hctx0/tags+AF8-bitmap:00000040: ffff ffff ffff ff7f ffff ffff ffff ffff dm-1/hctx0/tags+AF8-bitmap:00000050: ffff ffff ffff ffff ffff ffff ffff ffff dm-1/hctx0/tags+AF8-bitmap:00000060: f3ff 1fe0 ffff f19f ffff ffff ffff ffff dm-1/hctx0/tags+AF8-bitmap:00000070: ffff fff7 9bff fff7 0fec 1300 00e0 1f01 dm-1/hctx0/tags+AF8-bitmap:00000080: ffff ffff ffff e189 ff0f 90ff ffff ffff dm-1/hctx0/tags+AF8-bitmap:00000090: ffff ffff ffff ffff ffff 0300 00fd 0780 dm-1/hctx0/tags+AF8-bitmap:000000a0: ffff ffff ffff ffff ff0f 0000 0000 5400 dm-1/hctx0/tags+AF8-bitmap:000000b0: ffff ffff ffff ffff ffff ffff ffff ff0f dm-1/hctx0/tags+AF8-bitmap:000000c0: ffff ffff ffff ff3f ffff ffff ffff 7f1c dm-1/hctx0/tags+AF8-bitmap:000000d0: ffff ffff ffff ffff ffff ffff ffff ffff dm-1/hctx0/tags+AF8-bitmap:000000e0: ffff ffff 0f00 0040 1de0 1400 3cdf 0300 dm-1/hctx0/tags+AF8-bitmap:000000f0: ffff ffff 1f1c 7cfb ffff ffff ffff 1fef dm-1/state:SAME+AF8-COMP+AHw-NONROT+AHw-IO+AF8-STAT+AHw-INIT+AF8-DONE+AHw-STATS+AHw-REGISTERED+AHw-QUIESCED dm-1/queue/scheduler:+AFs-none+AF0 bfq kyber mq-deadline dm-2 loop0 loop1 loop2 loop3 loop4 loop5 loop6 loop7 nullb0 nullb1 sda sdb sdc sdd sde sdf sdg sdh vda Bart.
