[Linux-cachefs] Preliminary tests

[Cesar Delgado]

I did, that was the 1st time I mounted CacheFS.  From then on I didn't 
run the echo command.  I just the results I sent were exactly in the 
order I did things starting when the machine 1st came up after I'd 
recompiled the kernel.  Then I installed the utils-linux RPM; fdisk the 
drive I wanted to put the cache on so I could take off the old 
partitions I had on there; and ran the command I sent in the previous email.
