Subject: io_uring: remove unneeded io_send_zc accounting
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=046fcc83ac1ba8747f0bcae13f5e433802735245;p=linux-2.6-microblaze.git

io_uring: remove unneeded io_send_zc accounting

zc->len and zc->buf are not actually used once you get to the retry
stage. The buffer remains in kmsg->msg.msg_iter, which is setup in
io_send_setup.
Note: it still seems needed in io_send due to io_send_select_buffer
needing it (for the len parameter).
