This is adding a second definition of _require_fsverity_corruption().
Probably a rebase error.
Also, is this hunk in the right patch? This patch is for adding btrfs/290;
however, btrfs/290 doesn't use _require_fsverity_corruption() anymore.

I think a good way to organize things would be to wire up the existing verity
tests for btrfs first, then to add the btrfs-specific tests at thet end of the
series. That would mean the above hunk would go earlier in the series, not with
btrfs/290. It's a little hard to review as-is, as the different hunks needed to
wire up the existing tests are mixed around in different patches.
