Re: [PATCH v2] exfat: speed up file creation in large directories

[Yang Wen]

Thank you for pointing these out.

You are right about the 255 UTF-16 code unit case.I overlooked this 
boundary condition.

The empty-entry hint can also become stale when an earlier entry is freed.
I will update the relevant rollback, unlink, rmdir, rename, and move paths
so that the next allocation can rediscover and reuse earlier holes.

I will fix both issues and reorganize the changes into a patch series in
the next revision.

Thanks again for the careful review.
