The Call for Proposals for the Linux Plumbers Conf 2012 is out. We're
looking for speakers to talk at the Virtualization microconference as
well as the main conference. The deadline for proposal submissions is

I see this is quite fresh. What are the plans here?
We're still discussing where the fix should be, but it certainly is a
kernel bug

I don't think that patch updates the block inode size. We'd need to
call fs/block_dev.c:revalidate_disk() instead of directly calling
cdi-disk-fops-revalidate_disk(cdi-disk).

These patches introduce safezero() to allocate chunks for a file and
write zeroes to them.
Not yet ready for merge; I don't understand the configure system yet
and don't know how to test for posix_fallocate() availability.
The second patch introduces a new variable, track_allocation_progress,
fragmentation for the chunk being
allocated.
For systems that don't support posix_fallocate(), fall back to safewrite().

This patchset makes use of the posix_fallocate() call to allocate
chunks of files whenever needed if it's available.
We fallback to using safewrite() if it's not available.
mmap() could be used instead of safewrite too; I have a patch in case
someone is interested in seeing it.

The best case to get a non-fragmented VM image is to have it allocated

The main problem with this change is that it'll make
