Just trivia:

Using #define pr_fmt(fmt) KBUILD_MODNAME ":%s: " fmt, __func__
generally produces smaller overall object size, especially
at 64 bit.

For instance, here's the size of netlink.o at 32 bit:

$ size drivers/infiniband/core/netlink.o.*
   text	   data	    bss	    dec	    hex	filename
   2663	    153	    736	   3552	    de0	drivers/infiniband/core/netlink.o.old
   2640	    153	    736	   3529	    dc9	drivers/infiniband/core/netlink.o.new

Also, I rarely find __func__ useful in message output.
It may be more useful for active development/debugging.
