Subject: [PATCH v3 17/22] kmsg_dumper: Introduce a new 'SOFT' dump reason
Date: Tue, 14 Dec 2010 13:30:27 -0800 [thread overview]
Message-ID: <20101214213026.17022.26883.stgit@mike.mtv.corp.google.com> (raw)
In-Reply-To: <20101214212846.17022.64836.stgit@mike.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>

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.
