Hi,
I report a benchmark result of this week on IPF using
ia64/xen-unstable and ia64/linux-2.6.18-xen.
- The following cset broke tap:aio.
863: blktap: don't access deallocated data
http://xenbits.xensource.com/linux-2.6.18-xen.hg?rev/464a925d73f1
Guests hung up while booting, so we used file instead of tap:aio.
- The issue that HVM domains cannot read the contents of HDD is fixed.

Hi Keir.
The xen 3.4 release is getting near. (I don't know how soon you're
planning to release 3.4.0)
So can you wait for me to create a new patch or can we revert
the patch for the 3.4 release?
Anyway the patch isn't a complete fix as I pointed out.
I'll look into this problem from the next Monday. But I'm not sure
I can create it so soon.
thanks,

Linux kernel isn't part of a Xen release. 3.4.0 is probably two weeks away.

Can you please try this patch?
linux/blktap: fix vma_close() for partial munmap.
the previous vma_close() didn't take partial
munmap into acount. This patch fixes it.

Thank you. I haven't reproduce it yet.
Do you have any logs without the patch?

linux/blktap: fix vma_close() for partial munmap.
vm_area_struct::vm_private_data is used
by get_user_pages() so that we can't override
it. So in order to make blktap work, set it
to a array of struct page*.
Without mm->mmap_sem, virtual mapping can be changed.
so remembering vma which was passed to mmap callback
is bogus because later the vma can be freed or changed.
So don't remember vma and put necessary infomations into
tap_blkif_t. and use find_vma() to get necessary vma's.

The issue was fixed.
I confirmed that both PV and HVM domains booted up.
Thank you.
