    Subjectpls help me
    Hi, all, 

    Recently I wrote a file-system under Linux. When mounting, it prints
    these messages. I use iget(sb, ino) to get the root inode.

    But when run into get_new_inode():wake_up(), it hangs there. Who could
    give me some hints?

    what the dmesg output:

    ==> vvfs_init()
    ==> vvfs_read_super(<NULL>)
    ==> vvfs_connect(, 52886)
    2, 38606, 956410048
    <== vvfs_connect()OK
    superblock ordinary filling ok
    ==> vvfs_alloc_inode()
    <== vvfs_alloc_inode()
    ==> vvfs_read_inode(c67fb000)
    get sb sock
    get inode fid
    root inode
    fetch inode OK
    set server info OK
