Subject: [Crash-utility] [PATCH]: gcore extension, anonymous union in inode struct
Date: Wed, 5 Sep 2012 12:29:43 +0200
Hi Crash people,
The gcore extension fails on the 3.4 kernel I'm using. It attempts to
find the offset of a member within the inode struct, but the member is
part of an anonymous union. This patch fixes the problem for me.
