[Qemu-block] [PATCH v2 0/7] curl: locking cleanups/fixes, coroutine conv

From: Paolo Bonzini
Subject: [Qemu-block] [PATCH v2 0/7] curl: locking cleanups/fixes, coroutine conversion, remove aio_poll
Date: Wed, 10 May 2017 16:31:58 +0200

Since the last patch in v1 didn't work, I bit the bullet and converted
the whole thing to coroutines (patches 4-6).  This in turns allows a more
elegant solution to wait for CURLStates to get free (patch 7).

I tested this by lowering CURL_NUM_STATES to 2.  With this change, the
buggy case triggers a couple times while booting a Fedora netinst image.


Paolo Bonzini (7):
  curl: strengthen assertion in curl_clean_state
  curl: never invoke callbacks with s->mutex held
  curl: avoid recursive locking of BDRVCURLState mutex
  curl: split curl_find_state/curl_init_state
  curl: convert CURLAIOCB to byte values
  curl: convert readv to coroutines
  curl: do not do aio_poll when waiting for a free CURLState
