The erofs_super_block has volume_name field. On the other hand,
mkfs.erofs is not supporting to set volume name.
This patch add volume-name setting support to mkfs.erofs.
Option keyword is similar to mkfs.vfat.
usage:
mkfs.erofs -n volume-name image-fn dir

Thanks for your patch! The patch itself generally looks good to me.
Just two minor ideas:
1) How about following mke2fs by using "-L volume-label" ?
https://www.man7.org/linux/man-pages/man8/mke2fs.8.html
2) If possible, how about adding a kernel ioctl for this if you have
more interest? I mean FS_IOC_GETFSLABEL.

Hi Gao
Thank you feedback!
>1) How about following mke2fs by using "-L volume-label" ?
>https://www.man7.org/linux/man-pages/man8/mke2fs.8.html
The mkfs.extX is using "-L volume-label".
The mkfs.vfat is using "-n volume-name".
I think both better.
You commented to "-L" is more better, I will change it.
>2) If possible, how about adding a kernel ioctl for this if you have more interest?
>I mean FS_IOC_GETFSLABEL.
It's interesting feature. I will try to work it.

Yeah, I tend to follow mke2fs if it has the similar
function if possible, since it's more widely used :)

Thanks a lot! Yet that is not urgent since 6.1 features are
already fixed, it needs to be landed in 6.2...

Subject: [PATCH] erofs-utils: mkfs: Add volume-label setting support
The on-disk erofs_super_block has the volume_name field. On the other
hand, mkfs.erofs doesn't support setting volume label.
This patch adds volume-label setting support to mkfs.erofs.
Option keyword is similar to mke2fs.
Usage:
mkfs.erofs -L volume-label image-fn dir
