From: Breno Leitao Date: Mon, 16 Oct 2023 13:47:46 +0000 (-0700) Subject: io_uring/cmd: return -EOPNOTSUPP if net is disabled X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d2cac3ec823798861f8f39b4aa0ec960ffa997b0;p=linux.git io_uring/cmd: return -EOPNOTSUPP if net is disabled Protect io_uring_cmd_sock() to be called if CONFIG_NET is not set. If network is not enabled, but io_uring is, then we want to return -EOPNOTSUPP for any possible socket operation. This is helpful because io_uring_cmd_sock() can now call functions that only exits if CONFIG_NET is enabled without having #ifdef CONFIG_NET inside the function itself.
