123 * @brief Mapping of ki_stat in struct kinfo_proc to the linux state
125 * The linux procfs state field displays one of the characters RSDZTW to
126 * denote running, sleeping in an interruptible wait, waiting in an
127 * uninterruptible disk sleep, a zombie process, process is being traced
128 * or stopped, or process is paging respectively.
130 * Our struct kinfo_proc contains the variable ki_stat which contains a
131 * value out of SIDL, SRUN, SSLEEP, SSTOP, SZOMB, SWAIT and SLOCK.
133 * This character array is used with ki_stati-1 as an index and tries to
134 * map our states to suitable linux states.
