    blkcg: kill blkio_list and replace blkio_list_lock with a mutex · bc0d6501
    Tejun Heo authored Apr 13, 2012
    
    
    With blkio_policy[], blkio_list is redundant and hinders with
    per-queue policy activation.  Remove it.  Also, replace
    blkio_list_lock with a mutex blkcg_pol_mutex and let it protect the
    whole [un]registration.
    
    This is to prepare for per-queue policy activation and doesn't cause
    any functional difference.
