From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx> I added tracking of most classes of objects which contribute to client's memory footprint and accouting along the similar lines as in Rob's msm code. Then printing it out to fdinfo using the drm helper Rob added. Accounting by keeping per client lists may not be the most effient method, perhaps we should simply add and subtract stats directly at convenient sites, but that too is not straightforward due no existing connection between buffer objects and clients. Possibly some other tricky bits in the buffer sharing deparment. So lets see if this works for now. Infrequent reader penalty should not be too bad (may be even useful to dump the lists in debugfs?) and additional list_head per object pretty much drowns in the noise.
