Hi all,
Regardless of this bisected issue, such commit and its description is
not good. Multiple entries are added and removed - no clue why. Was it
savedefconfig? Maybe yes, maybe no, who knows... If yes, it should be
reverted because savedefconfig is known to remove important features
*later* (vide DEBUG_FS in the past).
Instead, commit should explicitly explain for each item why this is
added or removed.
Best regards,
Krzysztof
