vs. removal with lockdep"), it appears to have false positives and
really shouldn't have been in the -rc series with the fixes anyway.

This reverts commit f4acfcd4deb1 ("debugfs: annotate debugfs handlers
vs. removal with lockdep"), it appears to have false positives and
really shouldn't have been in the -rc series with the fixes anyway.

Hi Chaitanya,
Please get the full CI run executed with this change, once its green we can
plan merge.

Just commented on "issues" (no real issues ) on BAT and asked to re-report but we really should use sometimes by-pass shards when we see regression on this magnitude. 
This has big impact on core/gem tests https://intel-gfx-ci.01.org/tree/drm-tip/index.html?testfilter=module%7Cgem%7Ccore 
Even on module load. I am leaning to break process and not wait to Full CI if someone who has merge rights (eg @Vivi, Rodrigo, @De Marchi, Lucas) agree here?

I think this is the convincing link:

Applied with ack on irc by Rodrigo.
