From: Vlad Yasevich Date: Tue, 17 Jan 2006 19:55:17 +0000 (-0800) Subject: [SCTP]: Fix bad sysctl formatting of SCTP timeout values on 64-bit m/cs. X-Git-Tag: v2.6.16-rc2~256^2~1^2~3 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8116ffad4180b39d7a755345c1fde09da83930c0;p=linux-2.6 [SCTP]: Fix bad sysctl formatting of SCTP timeout values on 64-bit m/cs. Change all the structure members that hold jiffies to be of type unsigned long. This also corrects bad sysctl formating on 64 bit architectures.
