Subject: Re: [patch 2/2] kprobes x86_64 quick fix mark-ro-data
Date: Tue, 19 Jun 2007 15:38:10 +0530	[thread overview]
Message-ID: <20070619100810.GA301@in.ibm.com> (raw)
In-Reply-To: <20070619100644.GA5478@in.ibm.com>

This patch is a quick fix for x86_64 to enable kprobes only if DEBUG_RODATA is
not configured. Since DEBUG_RODATA markes the kernel text pages as read-only.

Signed-off-by: Prasanna S P. <prasanna@in.ibm.com>
