Subject: io_uring: break links on shutdown failure
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a146468d76e0462393a3e15b77b8b3ede60e2d06;p=linux.git

io_uring: break links on shutdown failure

Ensure that the return value of __sys_shutdown_sock() is used to
potentially break links to the request, if we fail.

Fixes: 36f4fa6886a8 ("io_uring: add support for shutdown(2)")
