Subject: [PATCH v2 0/2] wait/9p: Account 9P RPC waiting time as I/O wait

This patch serie helps to attribute the time spent waiting for server
responses during 9P RPC calls to I/O wait time in system metrics. As a
result, I/O-intensive operations on a 9pfs mount will now be reflected
in the "wa" column instead of the "id" one of tools like top.

Changes since v1:
  - Convert a bunch of other 9P's wait_event_killable candidates

Remi Pommarel (2):
  wait: Introduce io_wait_event_killable()
  9p: Track 9P RPC waiting time as IO
