Subject: [PATCH RFC V10 2/18] x86/ticketlock: Don't inline _spin_unlock when using paravirt spinlocks
Date: Mon, 24 Jun 2013 18:10:45 +0530 [thread overview]
Message-ID: <20130624124045.27508.61000.sendpatchset@codeblue.in.ibm.com> (raw)
In-Reply-To: <20130624124014.27508.8906.sendpatchset@codeblue.in.ibm.com>
x86/ticketlock: Don't inline _spin_unlock when using paravirt spinlocks
From: Raghavendra K T <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.
