Subject: [PATCH RESEND 0/3] lib, stackdepot: check stackdepot handle before accessing slabs
Date: Wed, 15 Sep 2021 11:48:03 +1000	[thread overview]
Message-ID: <20210915014806.3206938-1-imran.f.khan@oracle.com> (raw)

This patch series consolidates the changes submitted and reviewed at [1]
and [2].
The patches at [1] and [2] were submitted separarely, but they have some
inter dependency (later patches were created on top of earlier ones).
As both sets are still under review, I have put them in a single
change set here, so that it can be reviewed/included together and also
to avoid automation build failures where git am fails because of absent
parent.

I have included Acked-by (from Vlastimil) and Reviewed-by (from Alexander)
tags obtained so far for these changes and have also addressed last review
comment from Vlastimil [3].

To summarize, the changes in this set are as follows:

PATCH-1: Checks validity of a stackdepot handle before proceeding
to access stackdepot slab/objects.

PATCH-2: Adds a helper in stackdepot, to allow users to print
stack entries just by specifying the stackdepot handle. It also
changes such users to use this new interface.   

PATCH-3: Adds a helper in stackdepot, to allow users to print
stack entries into buffers just by specifying the stackdepot handle and
destination buffer. It also changes such users to use this new interface.
