Subject: Fix the condition for stopping the writev_retry.
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=cca7fb2ab1111caae0265dff1a4434851369face;p=oweals%2Fubus.git

Fix the condition for stopping the writev_retry.

All iov's were sent only after the last were sent (iov_len == 0). We
could have 'cur_len == 0' if the sent iov's were sent wholly but not all
iov's were sent (how about all but the last).
