I've been looking more closely at this, and I think we can make things better by having the file system create a symlink from partition's holders directory to the file system's kobject (assuming the file system has a kobject, which most do not have). i.e., I'd add to ext4_fill_super() something like this: ret = add_symlink(bdev->bd_part->holder_dir, &ext4_kset->kobj); Currently, the holders directory will show links for md and devicemapper users of the block device. This would add a link if ext4 has the block device mounted. It's not a complete solution, but I think it would help, and as far as I can tell, it's in the spirit of how the holders directory was (partially) implemented. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
