* blkdiscard: add new commandLukas Czerner2012-09-281-0/+66
| | | | | | | | | | | | | blkdiscard is used to discard device sectors. This is useful for solid-state drivers (SSDs) and thinly-provisioned storage. Unlike fstrim this command is used directly on the block device. blkkdiscard uses BLKDISCARD ioctl or BLKSECDISCARD ioctl for the secure discard. All data in the discarded region on the device will be lost! Signed-off-by: Lukas Czerner <lczerner@redhat.com>

* blkdiscard: new commandKarel Zak2012-09-271-0/+66
Add to fstrim(8) code to support new discard BLKDISCARD and BLKSECDISCARD ioctls for block devices. The new command is only symlink to fstrim(8) as the both utils share some code and the basic ideas. Based on patch from Lukas Czerner <lczerner@redhat.com>. Signed-off-by: Karel Zak <kzak@redhat.com>
