linux - Inspect content of SLAB

Is there a way, preferably simple, how to inspect content of SLAB caches, especially dentry cache? I can imagine that this can be doable through kernel modules, but I highly doubt security would let me install custom-built kernel module to production system.



I'm 99% sure we're impacted by NSS dentry leak, but want to see cached entries to be 100% sure.



rhel, 2.6.32

Thanks!
