File fix_logrotation.patch of Package tuned.9566

From: Lidong Zhong <lzhong@suse.com>
Subject: log: add two options(log_file_count and log_file_maxbytes) in the main config file
References: bsc#1098395
Patch-Mainline: yes
Git-commit: 4791290f9b1a5c54fcc2c805b2cae0a7d1d9d08b
Git-repo: git://github.com/redhat-performance/tuned

Currently the logrotation is not configurable. On system with large
amount of cpus a tuned start creates a lot of entries and older log
entries are lost.
