a) i wouldn't fully trust ext4 for a few more months at least (for a system
partition, which you can toss and easily rebuild it's probably ready,
for a large, not otherwise backuped, data collection it may not yet be)
b) fallocate is relatively new, so you'd require a new libc and kernel
(same reason i used fadvise and not sync_file_range)
c) libc w/o proper kernel/fs support can emulate fallocate by prewriting zeros
to every single block -- not likely what you'd want; this makes above (b)
even more relevant.
