Subject: [PATCH v1 03/12] kmsg_dumper: Introduce a new 'SOFT' dump reason
Date: Tue, 02 Nov 2010 18:29:43 -0700	[thread overview]
Message-ID: <20101103012942.4641.6432.stgit@crlf.mtv.corp.google.com> (raw)
In-Reply-To: <20101103012917.4641.57113.stgit@crlf.mtv.corp.google.com>

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.

Signed-off-by: Mike Waychison <mikew@google.com>

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?
