Subject: [PATCH 0/2] Add FALLOC_FL_ZERO_RANGE to fallocate
Date: Tue, 12 Jun 2012 17:36:02 +0200 [thread overview]
Message-ID: <1339515364-17374-1-git-send-email-pbonzini@redhat.com> (raw)
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.
Paolo
