I am suspecting a memory leak in a kernel module that does layer 2
switching of data packets.
In the vmstat -m output the Num and Total keeps going up for the
kmalloc-512..
kmalloc-512 15232 15264 512 16
Is this a clear indication of leak in the kernel or can there be false
positives ?
Is there a way to trace the allocations of memory from different buckets of
kmalloc ?
