Subject: ustream-fd: stop trying to read when s->read_blocked is set.
X-Git-Url: http://git.archive.openwrt.org/?p=project%2Flibubox.git;a=commitdiff_plain;h=8964d77f806291bfbbad6a2e2b530c1838dec29c

ustream-fd: stop trying to read when s->read_blocked is set.

User's s->notify_read is called in ustream_fill_read().  If
s->read_blocked is set there, then stop reading more.
