Subject: [PATCH v2] mm/debug: __dump_page() prints an extra line
Date:   Mon, 11 Nov 2019 14:55:59 -0800
Message-ID: <20191111225559.19657-1-rcampbell@nvidia.com>
MIME-Version: 1.0

When dumping struct page information, __dump_page() prints the page type
with a trailing blank followed by the page flags on a separate line:

anon
flags: 0x100000000090034(uptodate|lru|active|head|swapbacked)

Fix this by using pr_cont() instead of pr_warn() to get a single line:

anon flags: 0x100000000090034(uptodate|lru|active|head|swapbacked)

Oops, fix the subject line.
