Subject: [PATCH 0/2] nilfs2: add support for FITRIM ioctl
Date: Sat, 15 Feb 2014 14:34:24 +0100 [thread overview]
Message-ID: <cover.1392470644.git.andreas.rohner@gmx.net> (raw)
Hi,
This patch adds support for the FITRIM ioctl, which allows user space
tools like fstrim to issue TRIM/DISCARD requests to the underlying
device. It takes a fstrim_range structure as a parameter and for every
clean segment in the specified range the function blkdev_issue_discard
is called.
Best regards,
Andreas Rohner
