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.
