At the cost of inviting some extra work. Because this patch used file_inode, the patch 6 needs to set the hint on two inodes. If we use bdev_file_inode, this whole thing becomes clean.
The idea of accessing block devices only in the F_SET_RW_HINT implementation is wrong because it involves a layering violation. With the current patch series data lifetime information is available to filesystems like Fuse. If the F_SET_RW_HINT implementation would iterate over block devices, no data lifetime information would be available to filesystems like Fuse. Bart.
