Subject: [PATCH 0/2] accel/tcg: Fix concurrent pthread_create() and munmap()
Date: Fri, 28 Oct 2022 14:42:25 +0200	[thread overview]
Message-ID: <20221028124227.2354792-1-iii@linux.ibm.com> (raw)

Hi,

This is a fix for the issue reported in [1].
Patch 1 is the fix itself, patch 2 is the test/reproducer.

By the way, I noticed that there is no code to free tb_jmp_cache, and
object_finalize(CPUState) is never called - in case of system emulation
this is fine, but what about linux-user?

Best regards,
Ilya
