  fuzz: add documentation to docs/devel/ (2020-02-22 08:26:48 +0000)

----------------------------------------------------------------
Pull request

This pull request contains a virtio-blk/scsi performance optimization, event
loop scalability improvements, and a qtest-based device fuzzing framework.  I
am including the fuzzing patches because I have reviewed them and Thomas Huth
is currently away on leave.

----------------------------------------------------------------

Alexander Bulekov (22):
  softmmu: move vl.c to softmmu/
  softmmu: split off vl.c:main() into main.c
  module: check module wasn't already initialized
  fuzz: add FUZZ_TARGET module type
  qtest: add qtest_server_send abstraction
  libqtest: add a layer of abstraction to send/recv
  libqtest: make bufwrite rely on the TransportOps
  qtest: add in-process incoming command handler
  libqos: rename i2c_send and i2c_recv
  libqos: split qos-test and libqos makefile vars
  libqos: move useful qos-test funcs to qos_external
  fuzz: add fuzzer skeleton
  exec: keep ram block across fork when using qtest
  main: keep rcu_atfork callback enabled for qtest
  fuzz: support for fork-based fuzzing.
  fuzz: add support for qos-assisted fuzz targets
  fuzz: add target/fuzz makefile rules
  fuzz: add configure flag --enable-fuzzing
  fuzz: add i440fx fuzz targets
  fuzz: add virtio-net fuzz target
  fuzz: add virtio-scsi fuzz target
  fuzz: add documentation to docs/devel/

Denis Plotnikov (1):
  virtio: increase virtqueue size for virtio-scsi and virtio-blk

Paolo Bonzini (1):
  rcu_queue: add QSLIST functions

Stefan Hajnoczi (7):
  aio-posix: avoid reacquiring rcu_read_lock() when polling
  util/async: make bh_aio_poll() O(1)
  aio-posix: fix use after leaving scope in aio_poll()
  aio-posix: don't pass ns timeout to epoll_wait()
  qemu/queue.h: add QLIST_SAFE_REMOVE()
  aio-posix: make AioHandler deletion O(1)
  aio-posix: make AioHandler dispatch O(1) with epoll
