Re: [Gluster-devel] fallocate

[Anand Avati]

If you call fallocate() over an existing region with data it shouldn't be wiped with 0s. You can also call fallocate() on a hole (in case file was ftruncate()ed to a large size) and that region should get "allocated" (i.e future write to an fallocated() region should NOT fail with ENOSPC).

BTW, does NetBSD have the equivalent of open_by_handle[_at]() and name_to_handle[_at]() system calls?

I note that glusterfs-3.5 branch requires fallocate(). That one does not
exist in NetBSD yet. I wonder if it can be emulated in userspace: this
is just about writing zeros to the new size, right?
