From be614086a4aff163d5aa0dc160638d1193b59cde Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Fri, 8 Feb 2008 04:18:30 -0800 Subject: proc: implement proc_single_file_operations Currently many /proc/pid files use a crufty precursor to the current seq_file api, and they don't have direct access to the pid_namespace or the pid of for which they are displaying data. So implement proc_single_file_operations to make the seq_file routines easy to use, and to give access to the full state of the pid of we are displaying data for. Signed-off-by: Eric W.
