Subject: [PATCH 0/3] find_next_iomem_res() fixes
Date: Mon, 24 Sep 2018 17:14:37 -0500	[thread overview]
Message-ID: <153782698067.130337.12079523922130875402.stgit@bhelgaas-glaptop.roam.corp.google.com> (raw)
In-Reply-To: <20180921073211.20097-2-lijiang@redhat.com>

Hi Lianbo,

These three patches are a possible replacement for your first patch
("[PATCH 1/3 v3] resource: fix an error which walks through iomem
resources").

I think the interface of find_next_iomem_res() can be improved to make
the code easier to read and also avoid the errors you're fixing.

I can't test these, so they've only been compiled.  If you can test
them and if you like them, feel free to incorporate them into your
series.  If not, just drop them (but please at least fix the same
error in walk_system_ram_range()).
