Lack of proper documentation in mkfs.f2fs manpage

[jiblime]

There is not enough explanation for what each option does in mkfs.f2fs.

Here are the supported features for one's current f2fs-tools version, in my case g-dev-test branch. This is not in the manpages for mkfs.f2fs.
ls /sys/fs/f2fs/features:

atomic_write block_zoned encryption extra_attr flexible_inline_xattr inode_checksum inode_crtime lost_found project_quota quota_ino sb_checksum
So...
cat /sys/fs/f2fs/features/*:

supported

Great!

But now I have to read f2fs-tools/mkfs/f2fs_format_main.c to know proper syntax.

The full list with correct wording: encrypt extra_attr flexible_inline_xattr inode_checksum inode_crtime project_quota compression

Notes: atomic_write and quota_ino are supported but not available as an option; compression is only available in this most recent commit. block_zoned is handled by the -m flag.

Proposed resolution: please help users understand the filesystem parameters better.
