    UBIFS: switch self-check knobs to debugfs · 81e79d38
    Artem Bityutskiy authored
    UBIFS has many built-in self-check functions which can be enabled using the
    debug_chks module parameter or the corresponding sysfs file
    (/sys/module/ubifs/parameters/debug_chks). However, this is not flexible enough
    because it is not per-filesystem. This patch moves this to debugfs interfaces.
    
    We already have debugfs support, so this patch just adds more debugfs files.
    While looking at debugfs support I've noticed that it is racy WRT file-system
    unmount, and added a TODO entry for that. This problem has been there for long
    time and it is quite standard debugfs PITA. The plan is to fix this later.
    
    This patch is simple, but it is large because it changes many places where we
    check if a particular type of checks is enabled or disabled.
