Sorry, I'm not sure what your are asking about here :) Can you please
elaborate more?


It's another artificail race that will cause part scan fail in
device_add_disk().

bdev_add() -> user can open the device now

disk_scan_partitions -> will fail is the device is already opened
exclusively

I'm thinking about set disk state before bdev_add()...

Oh, right. Yes, that should be a good fix to set GD_NEED_PART_SCAN before
calling bdev_add().

Glad to here that 😀
