With the introduction of zoned block device support in the kernel, accessing
discovering if a block device is zoned and accessing its zone layout information
does not require using SG_IO anymore. The file /sys/block/<dev>/queue/zoned
indicates the device zone model and the ioctls BLKREPORTZONE and BLKRESETZONE
defined in include/uapi/linux/blkzoned.h allow manipulating zones more easily.
This patch series brings in support for this new interface in place of the
direct SG_IO-zbc commands. In addition, it enforces some formtating options
for host-managed zoned block devices and straighten device zone layout checks
to make sure that the device can be used.
Finally, as discard does not result in write pointer zone reset, the ioctl
BLKRESETZONE is used during formatting to properly initialize all sequential
zones of the device.

SMR stands for "Shingled Magnetic Recording" which makes sense
only for hard disk drives (spinning rust). The ZBC/ZAC standards
enable management of SMR disks, but solid state drives may also
support those standards. So replace "SMR" with "zoned block device"
to avoid a HDD centric terminology.
In particular, rename the HMSMR feature to BLKZONED.

With the availability of the BLKREPORTZONE and BLKRESETZONE
ioctls, there is no need for using SG_IO to discover zoned
block devices characteristics. This simplifies the code.

Hi Damien,
I've resolved some conflicts in the patches, and finally integrated them on
top of our dev branch.
Could you take a look at them from the below url?
http://git.kernel.org/cgit/linux/kernel/git/jaegeuk/f2fs-tools.git/log/?h=dev
Thanks,

Checked and tested. This all looks good, no problems detected.
Thank you !
Please let me know how the kernel side integration goes. I can rebase on
the dev branch if needed. I used the f2fs code in Jens for-4.10/block
tree. That code was identical to f2fs tree master branch, apart from the
gc bug fix patch that I added.
Best regards.

You can find the merged patches below.
http://git.kernel.org/cgit/linux/kernel/git/jaegeuk/f2fs.git/log/?h=dev-test
And, I've started to test them, and it has been working with basic operations
so far.
I'll test bit more.
