What is proposed to be called 'preallocation=falloc' should fall back

What if user cares about time(writing zeroes or non-zeroes is
time-consuming) and wants falloc only sometimes? I think this is the
main difference between preallocation=falloc and preallocation=full.
Also posix_fallocate in glibc falls

Option preallocation=falloc preallocates disk space by calling
