From 2c03376d2db005869b1d4449097d51c96196529e Mon Sep 17 00:00:00 2001 From: Oleg Nesterov <oleg@redhat.com> Date: Thu, 9 Oct 2014 15:25:51 -0700 Subject: proc/maps: replace proc_maps_private->pid with "struct inode *inode" m_start() can use get_proc_task() instead, and "struct inode *" provides more potentially useful info, see the next changes.
