Then how to interpret slabinfo in 2.2.16 box? 
e.g. grep cache /proc/slabinfo

kmem_cache            32     42
skbuff_head_cache   2676   2730
dentry_cache       15626  16988
files_cache          103    108
uid_cache             10    127
slab_cache            85    126
what does those numbers mean?

Furthermore, are those cache info above reported as part of the total
cache in /proc/meminfo ? 

Lastly, which cache can be reclaimed, and which can't?

I am doing some memory measurements in 2.2.16 linux box. Thanks in advance!
