    Subject[PATCH 0/4] more on vfs-scale and vfs-automount
    Date
    I've put quite a bit of time into testing 2.6.38-rc and, given the
    time frame, and update is needed. The included patch series much
    improves the behaviour of autofs under load.

    I first thought the dentry leak you found was not the cause of the
    BUG() I was seeing but that appears to not be the case. I'm not
    seeing the BUG() at shutdown when umounting any more.

    I am still seeing occassional incorrect ENOENT returns. They must be
    comming from the VFS or the daemon as I've changed almost all the
    ENOENT returns in the autofs module to identify where it's comming
    from.

    Anyway, all, please review.
