commit 40d344ec5ee440596b1f3ae87556e20c7197757a

    xfs: mark the xfssyncd workqueue as non-reentrant
    
    On a system with lots of memory pressure that is stuck on synchronous inode
    reclaim the workqueue code will run one instance of the inode reclaim work
    item on every CPU. which is not what we want.  Make sure to mark the
    xfssyncd workqueue as non-reentrant to make sure there only is one instace
    of each running globally.  Also stop using special paramater for the
    workqueue; now that we guarantee each fs has only running one of each works
    at a time there is no need to artificially lower max_active and compensate
    for that by setting the WQ_CPU_INTENSIVE flag.
