Subject: [PATCH 0/3] percpu_ida: support to export allocation/free information
Date: Tue, 29 Apr 2014 22:53:50 +0800	[thread overview]
Message-ID: <1398783234-7062-1-git-send-email-tom.leiming@gmail.com> (raw)

Hi,

These patches support to export percpu_ida allocation/free information
via sysfs, so that percpu_ida performance can be monitored, and
at least two use cases:

- some parameters(such as percpu_max_size) from its users are very
sensitive to performance

- the data is helpful for verifying patches which try to improve
percpu_ida


Thanks,
--
Ming Lei
