    GFS2: Make writeback more responsive to system conditions · 4667a0ec
    Steven Whitehouse authored
    This patch adds writeback_control to writing back the AIL
    list. This means that we can then take advantage of the
    information we get in ->write_inode() in order to set off
    some pre-emptive writeback.
    
    In addition, the AIL code is cleaned up a bit to make it
    a bit simpler to understand.
    
    There is still more which can usefully be done in this area,
    but this is a good start at least.
