190  * |0|    library    |                    reason                   |
193  * A few of the reason bits are reserved as flags with special meaning:
197  *                   | rflags| |          reason                   |
203  * The reason flags are part of the overall reason code for practical
205  * reason codes in different numeric ranges.
207  * The currently known reason flags are:
209  * ERR_RFLAG_FATAL      Flags that the reason code is considered fatal.
211  *                      is also the code for ERR_R_FATAL (that reason
212  *                      code served the dual purpose of flag and reason
214  * ERR_RFLAG_COMMON     Flags that the reason code is common to all
225  * As expressed above, RFLAGS and REASON overlap by one bit to allow
226  * ERR_R_FATAL to use ERR_RFLAG_FATAL as its reason code.
235  * Reason flags are defined pre-shifted to easily combine with the reason
277  * ERR_PACK takes reason flags and reason code combined in |reason|.
