From e92e113cabc1d3e47dc4740a814adb413f022e2f Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 5 Dec 2013 12:28:02 -0500 Subject: [PATCH] netprio_cgroup: convert away from cftype->read_map() In preparation of conversion to kernfs, cgroup file handling is being consolidated so that it can be easily mapped to the seq_file based interface of kernfs. cftype->read_map() doesn't add any value and being replaced with ->read_seq_string(). Update read_priomap() to use ->read_seq_string() instead. This patch doesn't make any visible behavior changes.
