This could be removed, it's always 0 (see gpu_memory_manager.cc comments)

[sohanjg, 2015/11/13 07:30:44]

Done.

 
-  // The number of managed memory clients.
-  size_t client_count;
-
   // The number of context groups.
   size_t context_group_count;
 
   // The number of visible windows.
   uint32 window_count;

This could be removed too. It's not set anywhere (and actually uninitialized)

[sohanjg, 2015/11/13 07:30:44]

Done.
