LRU-WT file system
What is it?
The LRU-WT file system is a stackable file
system that provides a least-recently-used write-through (LRU-WT)
cache to any SPIN file system.
How does it work?
It doesn't, yet.
How will it work, then?
In the current design, you will mount a LRU-WT file system much like
any other file system, only instead of giving it the name of a
physical device to mount, you give it the name of a directory to
"stack" onto.
For example, typing
mount lruwt /cache /sampledir
will create a LRU-WT file system at cache. It will be
stacked on the directory sampledir. You can then bang away
at cache to your heart's content. It will attempt to satisfy
all read requests from its memory pool. If it can't, it will pass the
request on to sampledir and stash the answer away in the cache.
