SubjectRe: Is ReiserFS really a journaling file system, or is it really just a synchronous-metadata file system like BSD FFS?
Hi,

That's an application problem. For kernel.org, you may well have
multi-megabyte files which are created gradually over quite some
time as ftp uploads take place: do you expect the filesystem to be
able to tell the difference between a successful and an unsuccessful
upload and delete the file if it went wrong?

In this sort of case, you want the application to create a temporary
file, fsync it, and then rename it to its final destination if you
want the consistency of the final file to be guaranteed.
