/proc/<pid>/statm appears to always report 0 for 'lrs' (the fifth number, which comments suggest has to do with how many pages of shared libraries the process is using). I think this is because the get_statm() routine in fs/proc/array.c is using an old and now obsolete test for this. Here's a patch against 2.0.33 to change it to something deduced from examining how task_mem() appears to do it.
Possibly the /proc/<pid>/statm interface is obsolete, but I hope not; it appears to give some information not readily available from elsewhere (particularly the total size vs resident pages information).
