[Qemu-devel] [PATCH 0/2][RFC?] Remove SIGUSR2 from posix-aio

[Frediano Ziglio]

Now that iothread is always compiled sending a signal seems only an
additional step. This patch also avoid writing to two pipe (one from signal
and one in qemu_service_io).

Tested and works correctly with KVM enabled. Performances are only sligthly
better (as I expected). strace output is more readable.

Doubts:
- any sense having two patches and not only last one?
- comment is perhaps wrong as is also affect main core
- is ok if KVM is disabled? more testing required

Frediano Ziglio (2):
  block: avoid storing a constant in qemu_paiocb structure
  block: avoid SIGUSR2
