Subject: [patch 0/3] Text Section Edit Lock
Date: Mon, 18 Jun 2007 17:58:46 -0400 [thread overview]
Message-ID: <20070618215846.247539382@polymtl.ca> (raw)
Hi,
This code adds locking around text section modifications. It can be used by
paravirt/alternatives, kprobes and eventually the immediate values to:
A - synchronize dynamic code patching
B - make sure the pages are writable
I only provided the i386 version, but it could be easily ported to other
architectures.
It applies at the end of the 2.6.22-rc4-mm2 series in the following order:
text-edit-lock-i386.patch
text-edit-lock-alternative-i386.patch
text-edit-lock-kprobes-i386.patch
Comments are welcome, (testing is welcome too)
Mathieu
