This commit adds a new reason called KMSG_DUMP_SOFT, which signifies that the system isn't really going down. This logic is used in a later commit that introduces the netoops driver. Signed-off-by: Mike Waychison --- Notes: It is also possible that we not introduce KMSG_DUMP_SOFT, and simply overload the existing KMSG_DUMP_OOPS reason, but I figured that this would be cleaner. --- include/linux/kmsg_dump.h | 1 + 1 files changed, 1 insertions(+), 0 deletions(-) diff --git a/include/linux/kmsg_dump.h b/include/linux/kmsg_dump.h index a229acc..0abc2d7 100644 --- a/include/linux/kmsg_dump.h +++ b/include/linux/kmsg_dump.h @@ -20,6 +20,7 @@ enum kmsg_dump_reason { KMSG_DUMP_OOPS, KMSG_DUMP_PANIC, KMSG_DUMP_KEXEC, + KMSG_DUMP_SOFT, }; /** -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
