If I see the output of cat /proc//smaps, I find that there are some memory regions with which no read/write/execute permissions have been associated. Also these region are mapped to inode number 0.

I wanted to know how does a region end up in such a state? Is it some sort of memory leak?

Can these regions be ever used again by the process?
