Hi,guys. Does exfat-nofuse can support linux fallocate or posix fallocate operation?

Here is some patches for linux vfat support fallocate: https://patchwork.kernel.org/patch/1589161/

Are you interested in the ftruncate() operation? The fallocate() operation?

These are two distinct operations. ftruncate() is simply set the size of file X to Y; whereas fallocate() is set the size of file X to Y and ensure space is allocated so subsequent writes will not fail.

I was about to close the issue with "closing old requests." Lets wait for answer for few days...

Sorry for my mistake, I found some problem with samba(strict allocate = yes) for exFAT/vFAT system, because lost fallocate syscall on exFAT/vFAT partitions.
