FWIW, SUSE patches coreutils (patch attached) to use fallocate when
sparse=never or non-sparse files with sparse=auto (!make_holes in
copy.c(copy_reg). But as Eric wrote in the above thread, it would need a
gnulib module for a correct implementation.
BTW, biggest win is for ocfs2 as it must take cluster wide locks on
fragmentation, which was the reason we added the patch.
