Hi,
When the file /proc/slabinfo does get updated?
I started new process and I was thinking mm_struct active objects should be increased but it stays constant.
Program:
Hello.c
int main(){
printf("Welcome to SI-LUNX\n");
sleep(100);
return 0;
}
Output Before staring process:
#cat /proc/slabinfo | grep mm_struct
mm_struct 52 64 512 8 1 : tunables 0 0 0 : slabdata 8 8 0
# ps -fu root | wc
70 615 4645
Started process in another shell (shell was already open) /home/manoj/hello
Output after Starting process
# cat /proc/slabinfo | grep mm_struct
mm_struct 52 64 512 8 1 : tunables 0 0 0 : slabdata 8 8 0
# ps -fu root | wc
71 623 4711
Is it possible that parent(shell) and child (hello) using same mm_struct ?
I also tried running /home/manoj/hello&, but the result is same.
Is there something that I need to enable in my config file? Or there is a possible bug with update on /proc/slabinfo?
Note: /sys/kernel/slab/mm_struct/objects also shows same result.
