Not clear why we need to change this very fine name ?

SLAB_DESTROY_BY_RCU was only used by few of us, we know damn well what
it means.

Consider we wont be able to change it in various web pages / archives /
changelogs.

The reason I proposed this change is that I ran into some people last
week who had burned some months learning that this very fine flag
provides only type safety, not identity safety.

Other proposals?

Bung hunting requires scrapping git log, in particular in areas touching
RCU (not exactly trivial stuff :) :) :) )

git log | grep SLAB_DESTROY_BY_RCU 

A Google search on SLAB_DESTROY_BY_RCU finds ~4600 results.

If we rename SLAB_DESTROY_BY_RCU by XXXXXXXX, someone trying to see
prior patches or articles about XXXXXXXX mistakes will find nothing.

So please leave comments giving the old name ( SLAB_DESTROY_BY_RCU ) and
save time for future hackers.

Thanks.
