Subject: [PATCH 0/4] Some trivial live update fixes
Date: Mon, 23 Jun 2025 18:22:31 +0800	[thread overview]
Message-ID: <20250623102235.94877-1-zhenzhong.duan@intel.com> (raw)

Hi

These are trivial VFIO live update fixes in corner cases.

1) open /dev/vfio/vfio fail trigger SIGSEGV
2) mdev hotplug trigger qemu abort
3) potential SIGSEGV when unmap-all-vaddr failed
3) potential vfio_container_post_load failure

Thanks
Zhenzhong
