Hi All,
I played a little bit around with kmem_cache_alloc() and
kmem_cache_create() and figured out that it only appears
in /proc/slabinfo if I reserve a specific amount of memory.
Isn't it always preferable to precache space for often used
structs even for small structs?
I'm not sure whether I understood it right how it works.
But how does the kernel know for how many structs he should
preallocate memory?
Best regards
Jannik Becher
