Unless debugfs is disabled, like on Android, which is the real problem

trying to solve.

Then use some other filesystem to place your relay file in.  A relay
file is not a file that userspace should rely on for normal operation,
so why do you need it at all?

What tools/operation requires access to this file that systems without
debugfs support is causing problems on?

(trimmed some lists)

For the ath drivers (as well as the out-of-tree Android driver) it is 
being used for RF spectral scan which produces a large amount of data 
that is processed by a userspace analysis application.

I've been looking for an alternate filesystem to use, but am not finding 
anything where it appears easy to get a parent dentry, so any clues for 
the clueless (me) would be appreciated.
