X-Git-Tag: v10.2.0-rc1~5^2~4
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b0cc742f8475398467eaf85f1d3692d215465327;p=thirdparty%2Fqemu.git

blkreplay: Run BH in coroutine’s AioContext

While it does not matter in which AioContext we run aio_co_wake() to
continue an exactly-once-yielding coroutine, making this commit not
strictly necessary, there is also no reason why the BH should run in any
context but the request’s AioContext.
