module: move __module_get and try_module_get() out of line.
With the preempt, tracepoint and everything, it's getting a bit chubby. For an Ubuntu-based config: Before: $ size -t `find * -name '*.ko'` | grep TOTAL 56199906 3870760 1606616 61677282 3ad1ee2 (TOTALS) $ size vmlinux text data bss dec hex filename 8509342 850368 3358720 12718430 c2115e vmlinux After: $ size -t `find * -name '*.ko'` | grep TOTAL 56183760 3867892 1606616 61658268 3acd49c (TOTALS) $ size vmlinux text data bss dec hex filename 8501842 849088 3358720 12709650 c1ef12 vmlinux Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (made all out-of-line)
