Subject: [PATCH 0/2] vunmap and debug objects
Date: Fri, 13 Apr 2018 17:03:52 +0530	[thread overview]
Message-ID: <> (raw)

I'm not entirely sure, how debug objects are really
useful in vmalloc framework.

I'm assuming they are useful in some ways. So, there
are 2 issues in that. First patch is avoiding possible
race scenario and second patch passes _proper_ args
in debug object APIs. Both these patches can help
debug objects to be in consistent state.

We've observed some list corruptions in debug objects.
However, no claims that these patches will be fixing

If one has an opinion that debug object has no use in
vmalloc framework, I would raise a patch to remove
them from the vunmap leg.
