[PATCH] lib/rwsem.c: un-inline rwsem_down_failed_common()
Un-inlining rwsem_down_failed_common() (two callsites) reduced lib/rwsem.o
on my Athlon, gcc 4.1.2 from 5935 to 5480 Bytes (455 Bytes saved).
I thus guess that reduced icache footprint (and better function caching) is
worth more than any function call overhead.
