[PATCH 0/6] qemu-iotests fixes for Kevin's block tree

Posted by Stefan Hajnoczi 11 months, 1 week ago

Kevin merged several of my outstanding multi-queue block layer patch series and
found that qemu-iotests -qcow2 was broken. This patch series fixes the block branch.

Most of the fixes are easy but the NBD server required deeper debugging and
thread-safety fixes. The NBD server patches can be inserted before "aio: make
aio_context_acquire()/aio_context_release() a no-op" to preserve bisectability.
The other patches are fixups that can be squashed into the original patches.

Stefan Hajnoczi (6):
  fixup block-coroutine-wrapper: use qemu_get_current_aio_context()
  fixup block: remove AioContext locking
  fixup scsi: only access SCSIDevice->requests from one thread
  nbd/server: avoid per-NBDRequest nbd_client_get/put()
  nbd/server: only traverse NBDExport->clients from main loop thread
  nbd/server: introduce NBDClient->lock to protect fields
