    UBIFS: switch to dynamic printks · 56e46742

    Switch to debugging using dynamic printk (pr_debug()). There is no good reason
    to carry custom debugging prints if there is so cool and powerful generic
    dynamic printk infrastructure, see Documentation/dynamic-debug-howto.txt. With
    dynamic printks we can switch on/of individual prints, per-file, per-function
    and per format messages. This means that instead of doing old-fashioned
    
    echo 1 > /sys/module/ubifs/parameters/debug_msgs
    
    to enable general messages, we can do:
    
    echo 'format "UBIFS DBG gen" +ptlf' > control
    
    to enable general messages and additionally ask the dynamic printk
    infrastructure to print process ID, line number and function name. So there is
    no reason to keep UBIFS-specific crud if there is more powerful generic thing.
