POHMELFS abbreviation.

POHMELFS stands for Parallel Optimized Host Message Exchange Layered File System.

And it has a metadata cache on client now. It contains just pohmelfs inodes, which are indexed by three tuples: first contains of name hash, parent inode number and length of the string (this guarantees, that there will be no identical tuples), second tuple is inodes number and the last one is offset in the address space of the parent.
Cache update operation is independant from its usage, althoguh both are guarded by the same lock.
