Subject: [PATCH V13 02/14] x86/ticketlock: Don't inline _spin_unlock when using paravirt spinlocks
Date: Fri, 9 Aug 2013 19:51:50 +0530 [thread overview]
Message-ID: <1376058122-8248-3-git-send-email-raghavendra.kt@linux.vnet.ibm.com> (raw)
In-Reply-To: <1376058122-8248-1-git-send-email-raghavendra.kt@linux.vnet.ibm.com>
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.

Paravirtualized spinlocks allow a pvops backend to replace the
spinlock implementation with something virtualization-friendly
