Subject: [PATCH 0/3] /proc/kmem fixes and hwpoison bits v2
Date: Wed, 16 Sep 2009 09:39:39 +0800	[thread overview]
Message-ID: <20090916013939.656308742@intel.com> (raw)

Hi Andrew and Kame,

Here are the 3 updated bug fix/cleanup patches for kmem.  Comments are welcome.

Changes since v1:
- change vread()/vwrite() prototype (proposed by Kame)
- include Kame's is_vmalloc_or_module_addr() check and use Hugh's -ENXIO.
- I decided not to use __GFP_ZERO, since the buf will be reused in the loop,
  so it would be better for vread to zero-fill it each time.
- removed the hwpoison checks for vmalloc pages. It seems that vread/vwrite
  could be simplified to handle one single page, and the hwpoison bits can be
  considered after that.

Thanks,
Fengguang
