Hello all,
          What exactly does each of these vm objects means with respect to*
/proc/<pid>/map*

vnode
default
device
swap
physical

And given that below are the fields corresponding to each entry in
*/proc/<pid>/map* ,what exactly does *flags* mean, i,e *the field after
reference count and before COW*

*start ,end ,RES ,PRES ,offset ,protection_flags ,shadow_count
> ,reference_count ,flags ,COW ,access ,type ,charged, charged uid*

Here is the code to the /proc/<pid>/map filler -->
https://github.com/freebsd/freebsd/blob/9561dc969d120d90918ddce5b82604ca349d592c/sys/fs/procfs/procfs_map.c#L219



Thank you,
-Shamantha.
