From e377c38ca7f5a55a7ed8ebd4486abcf4d39f4fd6 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Fri, 8 Feb 2019 11:40:17 -0700 Subject: io_uring_enter: don't expose sigset_size argument Applications should not need to care about this, we can pass it in ourselves. Once the libc support is there, we won't expose this parameter either.
