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. -- Libvir-list mailing list Libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
