In contrast to file-posix, however, they have not supported preallocated truncation so far. This series brings their truncation code to feature parity with their creation code in this regard. Note that I do not have a test setup for either of the two drivers, so I do not actually know whether this works. Anyone with a setup is more than welcome to test this series.
