This patch adds the FALLOC_FL_ZERO_RANGE operation mode to fallocate, resembling the similar XFS ioctl. The new mode can be used with or without FALLOC_FL_KEEP_SIZE, but of course not together with FALLOC_FL_PUNCH_HOLE.
Other filesystems can then provide the same functionality with a standard system call.
