Subject: [PATCH] mm/debug:
Date: Mon, 11 Nov 2019 14:49:35 -0800	[thread overview]
Message-ID: <20191111224935.19464-1-rcampbell@nvidia.com> (raw)

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)
