[PATCH v3 0/2] KVM: selftests: fix races in dirty log test

From: Peter Xu
Date: Sat Apr 17 2021 - 10:36:18 EST

Please consider overtake the previous v2 [1] of this patch which is a single
patch, also please find more information in the commit message of each patch.

I kept the versioning since it solves the same problem, but mostly rewritten.

I've run a few hours of below workloads in parallel to test this patch:

(1) while :; do taskset -c 1 ./dirty_log_test; done
(2) taskset -c 1 bash -c "while :; do :; done"

Review comments are greatly welcomed.
