It is for zeroing an existing section of a file while retaining the allocated space, not for extending or truncating the file. It's the same reason that FALLOC_FL_PUNCH_HOLE must have FALLOC_FL_KEEP_SIZE set. Also, a minor nit, but you should credit where this code has originated from in the commit messages, and describe the use case for requiring it. i.e. based on: http://permalink.gmane.org/gmane.linux.file-systems/62449 Cheers, Dave. -- Dave Chinner david@xxxxxxxxxxxxx _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
