    Btrfs: make a lockdep class for each root · 85d4e461
    Chris Mason 提交于
    This patch was originally from Tejun Heo.  lockdep complains about the btrfs
    locking because we sometimes take btree locks from two different trees at the
    same time.  The current classes are based only on level in the btree, which
    isn't enough information for lockdep to figure out if the lock is safe.
    
    This patch makes a class for each type of tree, and lumps all the FS trees that
    actually have files and directories into the same class.
