Description

We are seeing high usage from the ldiskfs_inode_cache slab. This filesystem has ~430M files in it, and currently we are utilizing ~90GB of ldiskfs_inode_cache.

We are currently undergoing testing to create 500M files into a test filesystem, wanted to break this out from LU-4570. More data to come.
