It's a bit scary tho. Working inode->i_dentry or dentry->d_alias crosses multiple sb's. sysfs isn't too greedy about dcache/icache. Only open files and directories hold them and only single copy of sysfs_dirent is there for most nodes. Wouldn't it be better to stay on the safer side and use separate inode hierarchy?
