    sysfs, kernfs: make super_blocks bind to different kernfs_roots · df394fb5
    Tejun Heo authored
    kernfs is being updated to allow multiple sysfs_dirent hierarchies so
    that it can also be used by other users.  Currently, sysfs
    super_blocks are always attached to one kernfs_root - sysfs_root - and
    distinguished only by their namespace tags.
    
    This patch adds sysfs_super_info->root and update
    sysfs_fill/test_super() so that super_blocks are identified by the
    combination of both the associated kernfs_root and namespace tag.
    This allows mounting different kernfs hierarchies.
