Subject: Re: [PATCH v4] printk: Userspace format enumeration support

Thanks for all your feedback, Petr and Steven. :-)

Petr, I believe this is a comprehensive checklist of everything we discussed 
for v5 -- any chance you could double check I'm not missing anything you folks 
wanted? Thanks!

- Use seq_file iterator again instead of simple_open + size
- Remove debugfs file first to avoid ENOENT
- Tear down datastructures if debugfs fails
- Human readable output format
- Display file/line
- Rename to CONFIG_PRINTK_INDEX, or... something
- Move to another file, kernel/printk/debug_formats.c or similar
- Use `struct module *mod` instead of calling it module
- Add documentation for printk_fmt_sec (or whatever it will be called)
- Rename things to pf_, pi_, or something
- See if it's safe to pass a printk_fmt_sec to seq_file instead of a module
- Handle cont + level
- Don't expose level/KERN_SOH directly
