Subject: [PATCH 0/1] block: Manage bio references so the bio persists until necessary
Date: Thu, 30 Jan 2020 19:23:41 -0800 [thread overview]
Message-ID: <[email protected]> (raw)
This patch addresses a bio reference count problem encountered while
debugging a different, use-after-free bug with the fio test below.
The original use-after-free bug is still hit however.
[global]
filename=/dev/nvme0n1
rw=randread
bs=4k
direct=1
time_based=1
randrepeat=1
gtod_reduce=1
[fiotest]
fio nvme.fio --readonly --ioengine=io_uring --iodepth 1024 --fixedbufs
--hipri --numjobs=$1 --runtime=$2
