Subject: [PATCH 0/4] Per-superblock dcache limitation

Hello,

Now that we've got per-sb dcache lru lists, I am proposing
through theses patches that each of those be size-limited.
The main use case I am targetting is containers, where we want
a container not to use more than a certain specified amount
of non-shrikable kernel memory. 

Comments welcome

Glauber Costa (4):
  Keep nr_dentry per super block
  limit nr_dentries per superblock
  dcache set size
  parse options in the vfs level
