Subject: [PATCH v4 0/4 (resend)] Optimize CONFIG_DEBUG_PAGEALLOC (x86 and s390)
Date: Wed, 3 Feb 2016 09:39:31 +0100 [thread overview]
Message-ID: <1454488775-108777-6-git-send-email-borntraeger@de.ibm.com> (raw)
In-Reply-To: <1454488775-108777-1-git-send-email-borntraeger@de.ibm.com>
Andrew, here is a resend as these patches were dropped as I also
had them on my linux-next branch (instead of a private one)
As CONFIG_DEBUG_PAGEALLOC can be enabled/disabled via kernel
parameters we can optimize some cases by checking the enablement
state.
I have done s390 and x86. Other architecture can follow as necessary.
Christian Borntraeger (4):
mm: provide debug_pagealloc_enabled() without CONFIG_DEBUG_PAGEALLOC
x86: query dynamic DEBUG_PAGEALLOC setting
s390: query dynamic DEBUG_PAGEALLOC setting
x86: also use debug_pagealloc_enabled() for free_init_pages
