Instead of inlining __mutex_lock_common() 5 times, once for each {state,ww} variant. Reduce this to two, ww and !ww. Then add __always_inline to mutex_optimistic_spin(), so that that will get inlined all 4 remaining times, for all {waiter,ww} variants. text data bss dec hex filename 6301 0 0 6301 189d defconfig-build/kernel/locking/mutex.o 4053 0 0 4053 fd5 defconfig-build/kernel/locking/mutex.o 4257 0 0 4257 10a1 defconfig-build/kernel/locking/mutex.o This reduces total text size and better separates the ww and !ww mutex code generation.
