[Devel] [PATCH 8/9] Small cleanup for xxx_put after evictor consolidation

[Pavel Emelyanov]

After the evictor code is consolidated there is no need in 
passing the extra pointer to the xxx_put() functions.

The only place when it made sense was the evictor code itself.

Maybe this change must got with the previous (or with the 
next) patch, but I try to make them shorter as much as 
possible to simplify the review (but they are still large 
anyway), so this change goes in a separate patch.
