[PATCH v2 0/4] Per-container dcache size limitation

Since v1, there is not too much new here.
I'm incorporating David's suggestion of calling the sb
shrinker, which will, in effect, prune the icache and
other sb related objects as well.

I am also keeping the mount based interface, since I
still believe it is the way to go. But I'm obviously
still open for suggestions. Some small corrections
were also made to it since v1. Specifically, bind
mounts are not allowed to alter the original sb dcache

Glauber Costa (4):
  factor out single-shrinker code
  Keep nr_dentry per super block
  limit nr_dentries per superblock
  parse options in the vfs level
