Message-Id: <1366146438-8815-5-git-send-email-dborkman@redhat.com>

From: Daniel Borkmann <dborkman@...hat.com>
To: davem@...emloft.net
Cc: netdev@...r.kernel.org, linux-sctp@...r.kernel.org
Subject: [PATCH net-next 4/9] net: sctp: sctp_outq: consolidate chars into bitfield
sctp_outq structure members fast_rtx, cork and empty are all
of type char. Consolidate them into a single __u8 bitfield since
they either carry 0 or 1. Have the rest 5 bits for future flags.
