Subject: [PATCH] net: Fix struct inet_timewait_sock bitfield annotation
Date: Mon, 19 Oct 2009 10:48:51 +0200 [thread overview]
Message-ID: <4ADC27F3.5050508@gmail.com> (raw)
commit 9e337b0f (net: annotate inet_timewait_sock bitfields)
added 4/8 bytes in struct inet_timewait_sock.
Fix this by declaring tw_ipv6_offset in the 'flags' bitfield
The 14 bits hole is named tw_pad to make it cleary apparent.
