As I wrote in my [PATCH 0/12], it applies on top of the pushdown
of the BKL into the get_sb operation, and I intend to submit it
to Linus with the full series.

I agree that this particular patch is a bit pointless because
all it does is to undo the change from the pushdown. I guess
that at the time when the first patch was written, the BKL
was still present in other parts of capifs.
