Subject: compat_ioctl: handle SIOCOUTQNSD
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9d7bf41fafa5b5ddd4c13eb39446b0045f0a8167;p=linux.git

compat_ioctl: handle SIOCOUTQNSD

Unlike the normal SIOCOUTQ, SIOCOUTQNSD was never handled in compat
mode. Add it to the common socket compat handler along with similar
ones.

Fixes: 2f4e1b397097 ("tcp: ioctl type SIOCOUTQNSD returns amount of data not sent")
