Subject: [PATCH 0/1] Memory usage limit notification addition to memcg

Hello all,

The following patch introduces memory usage limit notification capability to
the Memory Controller cgroup. It is a reworked version of a patch sent by Dan
Malek in April 2009.

The major difference between this and original patches is a modified method of
notification threshold setting. The original patch implemented threshold as a
percentage of the memory controller limit. During following discussion it's
been decided to change percentage to an absolute number representing the
minimal amount of memory that should be available below the limit. The
following patch implements this method along with various clean-ups and style
changes.

Thanks,
Vlad.
