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