Hi all,

I want to calculate the total kernel memory usage.

cat /proc/meminfo
MemTotal:      4131168 kB

Hugepagesize:     2048 kB
DirectMap4k:      4096 kB
DirectMap2M:    913408 kB

so I want to know the method by which I can know the amout of memory
kernel is using at any instance of time. How can i find this.
since as far as i know vmallocused =vmalloc allocation+ ioremap. also
ioremap can be allocated multiple times. So is there any method to do
exact calculation.

Thanks
