Hi,
With a ramdump of a system with 386MB of available memory, "kmem -s"
shows something like this
CACHE NAME OBJSIZE ALLOCATED TOTAL SLABS SSIZE
dd801c00 kmalloc-2048 2048 670869 670960
41935 32k
The memory occupied by objects go beyond the total system memory if we
use the above numbers to calculate that. I think the output is wrong
because with SLUB, slabs can be of different sizes depending on the
order of allocation. And here objects are calculated considering slabs
are of fixed size.
The attached patch worked for me.
Thanks,
Vinayak
