-Subject: [PATCH 1/2] osdep: Add runtime OFD lock detection
-
-Build time check of OFD lock is not sufficient and can cause image open
-errors when the runtime environment doesn't support it.
-
-Add a helper function to probe it at runtime, additionally. Also provide
-a qemu_has_ofd_lock() for callers to check the status.

-Subject: [PATCH 2/2] file-posix: Do runtime check for ofd lock API
-
-It is reported that on Windows Subsystem for Linux, ofd operations fail
-with -EINVAL. In other words, QEMU binary built with system headers that
-exports F_OFD_SETLK doesn't necessarily run in an environment that
-actually supports it:
-
-$ qemu-system-aarch64 ... -drive file=test.vhdx,if=none,id=hd0 \
-    -device virtio-blk-pci,drive=hd0
-qemu-system-aarch64: -drive file=test.vhdx,if=none,id=hd0: Failed to unlock byte 100
-qemu-system-aarch64: -drive file=test.vhdx,if=none,id=hd0: Failed to unlock byte 100
-qemu-system-aarch64: -drive file=test.vhdx,if=none,id=hd0: Failed to lock byte 100
-
-As a matter of fact this is not WSL specific. It can happen when running
-a QEMU compiled against a newer glibc on an older kernel, such as in
-a containerized environment.
-
-Let's do a runtime check to cope with that.

-Subject: [PATCH 4/4] Add support for VM suspend/resume for TPM TIS
-
-Extend the TPM TIS code to support suspend/resume. In case a command
-is being processed by the external TPM when suspending, wait for the command
-to complete to catch the result. In case the bottom half did not run,
-run the one function the bottom half is supposed to run. This then
-makes the resume operation work.
-
-The passthrough backend does not support suspend/resume operation
-and is therefore blocked from suspend/resume and migration.
-
-The CUSE TPM's supported capabilities are tested and if sufficient
-capabilities are implemented, suspend/resume, snapshotting and
-migration are supported by the CUSE TPM.
