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