PATCH 1/1 Create the caches with "calculated" names

Many code in the kernel needs to create the caches with some "formatted" names. E.g. the net/core/sock.c creates the caches with names
("request_sock_%s", proto->name)
dccp need caches like
("%s_hc_rx_sock", ccid_ops->ccid_name)
and so on.

The proposal is to create the generic method for creating such a caches. The code is spread across sl[auo]b, so maybe its better to move it to mm/util.c

The question is: does it worth sending to mainline?
