The immediate motivation is to avoid the race with zap_page_range()
when another node writes to the corresponding portion of the file,
similar to the situation with vmtruncate().  The thought was to
leverage locking within the distributed filesystem, but if the
race is solved locally, then, as you say, perhaps this is not 
necessary.

is said distributed filesystem open source by chance ?
