    GFS2: Umount recovery race fix · fe64d517
    Steven Whitehouse authored
    This patch fixes a race condition where we can receive recovery
    requests part way through processing a umount. This was causing
    problems since the recovery thread had already gone away.
    
    Looking in more detail at the recovery code, it was really trying
    to implement a slight variation on a work queue, and that happens to
    align nicely with the recently introduced slow-work subsystem. As a
    result I've updated the code to use slow-work, rather than its own home
    grown variety of work queue.
    
    When using the wait_on_bit() function, I noticed that the wait function
    that was supplied as an argument was appearing in the WCHAN field, so
    I've updated the function names in order to produce more meaningful
    output.
