From 0bc77381c1b1600e659eb7322c39d1753615722d Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Fri, 21 Jun 2013 08:58:21 -0400 Subject: seq_file: add seq_list_*_percpu helpers When we convert the file_lock_list to a set of percpu lists, we'll need a way to iterate over them in order to output /proc/locks info. Add some seq_list_*_percpu helpers to handle that. Signed-off-by: Jeff Layton Acked-by: J.
