block/amend: Keep strong reference to BDS (2022-03-04 17:15:33 +0100)
----------------------------------------------------------------
Block layer patches
- qemu-storage-daemon: Add --daemonize
- Fix x-blockdev-amend and block node activation code which incorrectly
executed code in the iothread that must run in the main thread.
- Add macros for coroutine-safe TLS variables (required for correctness
with LTO)
- Fix crashes with concurrent I/O and bdrv_refresh_limits()
- Split block APIs in global state and I/O
- iotests: Don't refuse to run at all without GNU sed, just skip tests
that need it
----------------------------------------------------------------
