Subject: MINOR: mux-h1: Try to wakeup the stream on output buffer allocation
X-Git-Tag: v2.1-dev3~141
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=660f6f34d7e6b64ed5cd7086b491a8113c7f8767;p=thirdparty%2Fhaproxy.git

MINOR: mux-h1: Try to wakeup the stream on output buffer allocation

When the output buffer allocation failed, we block stream processing. When
finally a buffer is available and we succed to allocate the output buffer, it
seems fair to wake up the stream.
