setup_bdev_super() already initializes sb->s_bdev and takes a
reference on the block device backing_dev_info when assigning sb->s_bdi.
nilfs_fill_super() takes another reference to the same
backing_dev_info and stores it in sb->s_bdi again. The extra
reference is not paired with a matching bdi_put(), since
generic_shutdown_super() releases sb->s_bdi only once.
Drop the redundant bdi_get() in nilfs_fill_super(). The single
reference taken by setup_bdev_super() is enough and is released
during superblock shutdown.
Fixes: c1e012ea9e ("nilfs2: use setup_bdev_super to de-duplicate the mount code")
