Subject: [PATCH v2 0/2] accel/tcg: Fix race condition in tb create/invalidate
Date: Fri, 7 Jul 2023 11:36:09 +0100 [thread overview]
Message-ID: <20230707103611.5906-1-richard.henderson@linaro.org> (raw)
Changes for v2:
Adjust the change to cpu_exec_longjmp_cleanup, which should now survive
user-only testing. I'm not really happy with it. I suggested two
alternatives in the block comment, but neither of them are trivial.
Please re-review, if you gave it a glance before. And if you have
any bright suggestions short of "use real exceptions", I'm all ears.
