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 -->
