[PATCH 0/2] Add FALLOC_FL_ZERO_RANGE to fallocate

From: Paolo Bonzini
Date: Tue Jun 12 2012 - 11:36:11 EST


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.
