From: Eric Dumazet <edumazet@google.com> mainline inclusion from mainline-v5.18-rc1 commit 7d959f6e978cbbca90e26a192cc39480e977182f category: bugfix bugzilla: 188015, https://gitee.com/openeuler/kernel/issues/I63WZE Reference: https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git/commit/?id=... -------------------------------- Calling mdelay(1000) from process context, even while a reboot is in progress, does not make sense. Using msleep() allows other threads to make progress.
