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.

If fscrypt is enabled, we need to convert the encrypted file name before

and make it returns the length of converted string.

On some systems '/proc/mounts' contains the entry '/dev/root'
as alias for the root device, while that alias doesn't actually
exist as symlink in /dev.
/proc/mounts:
/dev/root / f2fs rw,noatime,background_gc=on,user_xattr,acl,inline_data,extent_cache,active_logs=6 0 0
mount:
/dev/mmcblk1p1 on / type f2fs (rw,noatime,background_gc=on,user_xattr,acl,inline_data,extent_cache,active_logs=6)
If the root device is mounted RO, and we try to scan it, via
'fsck.f2fs /dev/mmcblk1p1', then fsck.f2fs exits because it can't
find the entry in /proc/mounts.
Try harder to identify the root device of the system first, and
in case we are operating on it, check also for '/dev/root' in mounts.
