specific stats. Added Makefile.am updates which I had missed in the
previous post.
New APIs to read controller specific statistics.
This patch introduces 3 new APIs which can be used to read controller
statistics iteratively. (Eg. stats from memory.stat etc)
Reading of stats is initiated by cgroup_read_stats_begin() API, which
returns the first stat of the requested controller in addition to returing
a handle that should be used in subsequent reads.
cgroup_read_stats_next() API can be used to read the remaining stats
one by one. This needs the handle returned by cgroup_read_stats_begin().
cgroup_read_stats_end() API will terminate the stats reading iteration
initiated by cgroup_read_stats_begin().
Changelog:
v2
- Update tests/Makefile.am so that it generates appropriate rules
for tests/read_stats.c in the Makefile. This is in addition to
the manual updates done to the generated file tests/Makefile.in.
v1
- cgroup_read_stats apis now work with relative cgroup path names instead
of absolute path names.
v0
- Initial post.

I reviewed the libcgroup code in the viewpoint of memory-leak and
found a lack of free(). This patch adds a free() call for error
handling.
