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!
