Not really. 'rst' can be easily mistaken for 'reset' and neither 
really tells me at a glance what they do. They are also quite 
tongue-twisters.

See my namespace analysis and suggestions from yesterday for a 
proper naming scheme.

The key i believe is to move away from this singular 'the world is 
all about checkpoint and restore', and move it to a IMHO clearer 
state_*() type of naming which really isolates all these kernel 
state save/restore management APIs from other kernel APIs. (See my 
mail from yesterday for details.)

kstate_*() would be another, perhaps even clearer naming scheme. 
I.e.:

  kstate_checkpoint_XYZ()
  kstate_restore_XYZ()
  kstate_collect_XYZ()
  kstate_dump_XYZ()
  kstate_image_XYZ()
  ...

Just _look_ at them - they are expressive at a glance, and 
reasonably short. That is the kind of first-time impression
we need, not a 'wtf?' moment.

I just checked, there's zero hits on "git grep \<kstate_" in the 
kernel, so it's a pristine namespace. IMHO, go wild ...
