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.
