Subject: [PATCH 0/4] process memory footprint info in proc/<pid>/[s|p]maps v2
Andrew,
Inspired by Matt Mackall's pagemap patches and ideas, I worked up these
textual interfaces that achieve the same goals. The patches run OK
under different sized reads.
1) Add PSS into the existing /proc/<pid>/smaps:
[PATCH 1/4] maps: PSS(proportional set size) accounting in smaps
2) Create /proc/<pid>/pmaps for page granularity mmap footprints:
[PATCH 2/4] maps: address based vma walking
[PATCH 3/4] maps: introduce generic_maps_open()
[PATCH 4/4] maps: /proc/<pid>/pmaps interface - memory maps in granularity of pages

In this new version, offset and len are changed to use hexical numbers.
Thank you,
