Subject: [PATCH RFC 3/6] epoll: Add definition for epoll_mod_wait structures
Date: Tue, 20 Jan 2015 17:57:55 +0800	[thread overview]
Message-ID: <1421747878-30744-4-git-send-email-famz@redhat.com> (raw)
In-Reply-To: <1421747878-30744-1-git-send-email-famz@redhat.com>

Two structs involved in the coming syscall is defined. Flags in epoll_mod_cmd
are reserved, which makes better word alignment and may allow future extension.
