Stop the HOSTFS filesystem from using iget() and read_inode(). Provide
hostfs_iget(), and call that instead of iget(). hostfs_iget() then uses
iget_locked() directly and returns a proper error code instead of an inode in
the event of an error.
hostfs_fill_sb_common() returns any error incurred when getting the root inode
instead of EINVAL.
Note that the contents of hostfs_kern.c need to be examined:
(*) hostfs_iget() should perhaps subsume init_inode() and hostfs_read_inode().
(*) It would appear that all hostfs inodes are the same inode because iget()
was being called with inode number 0 - which forms the lookup key.
