Understanding Anonymous Inode 0 Entries in /proc/pid/maps for Memory Usage in Embedded Linux
I'm investigating memory usage in my embedded Linux application using /proc/pid/maps. I'm confused by the entries with anonymous inode 0 in the perms column in particular. Seem to be some of the larger memory segments. Take a look : 
...
addr        end        perms    offset    dev   id       size        flags  name
...
f0000000-f0fffffff rw-p       0        0     0       1048576   anonvma   [heap]
...
...
addr        end        perms    offset    dev   id       size        flags  name
...
f0000000-f0fffffff rw-p       0        0     0       1048576   anonvma   [heap]
...
What does anonymous inode 0 entries mean? How does it contribute to my application's memory usage? @Middleware & OS
