Shouldn't this be Documentation/ABI/testing/sysfs-kernel-fadump_mem_reserved?

How about documenting fadump_mem_reserved and other sysfs attributes suggested
by you in a single file Documentation/ABI/testing/sysfs-kernel-fadump?

I wouldn't mind that but please do check if it is breaking a convention..

AIUI a file named like that would hold the documentation for the files
inside a directory called /sys/kernel/fadump.

And in fact that's probably where these files should live, rather than
just dropped directly into /sys/kernel.

Michael, could that be corrected now by introducing new sysfs files for FADump in
/sys/kernel/fadump/.

Also, duplicating current /sys/kernel/fadump_* files as /sys/kernel/fadump/* files
& eventually dropping /sys/kernel/fadump_* files sometime later..

Sent a patch series that adds fadump_mem_reserved sysfs file along with reorganizing
the existing fadump sysfs files.
