Subject[PATCH RFC V11 2/18] x86/ticketlock: Don't inline _spin_unlock when using paravirt spinlocks
x86/ticketlock: Don't inline _spin_unlock when using paravirt spinlocks

From: Raghavendra K T <>

The code size expands somewhat, and its better to just call
a function rather than inline it.

Thanks Jeremy for original version of ARCH_NOINLINE_SPIN_UNLOCK config patch,
which is simplified.
