Subject: vfs_aio_pthread: don't allow async opens when multi channel is enabled.
X-Git-Tag: tevent-0.11.0~1377
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=2c194c0bc61958b9f569b3808b45035c2de6caef;p=thirdparty%2Fsamba.git

vfs_aio_pthread: don't allow async opens when multi channel is enabled.

We will get this supported later, but for now just disable async
opens as fsp->mid may not belong the first xconn of client->connections.
