Hi all the kernel gurus, and folks in mailing lists,

This is a question about exporting 4KB+ text information via sysfs 
interface. I need advice on how to handle the problem.

Why do you think there is a problem?
As documented in Documentation/admin-guide/md.rst, the truncation at 1
page is expected and by design.

Ah, shouldn't that info also be in Documentation/ABI/ so that others can
easily find it?

thanks,

greg k-h
