Re: [PATCH v2 17/23] kmsg_dumper: Introduce a new 'SOFT' dump reason

Hi
It is a useful to be able to exercise kmsg_dumper implementations without
requiring a kernel oops or panic.  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.

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.

TODO: Make sure mtdoops and ramoops do something useful with this flag?
Yes. If userland explicitly want to log, we have no reason to refuse it. :)
But, I don't think KMSG_DUMP_SOFT is good name because _SOFT don't explain
anything.
