[Qemu-devel] [PATCH 0/4] block-backend: Queue requests while drained

Posted by Kevin Wolf 4 years, 9 months ago

This series fixes the problem that devices like IDE, which submit
requests as a direct result of I/O from the CPU thread, can continue to
submit new requests even in a drained section.

In order to avoid a dependency for this series, I borrowed a patch from
Max.

Kevin Wolf (3):
  block: Remove blk_pread_unthrottled()
  mirror: Keep target drained until graph changes are done
  block-backend: Queue requests while drained

Max Reitz (1):
  block: Reduce (un)drains when replacing a child
