Subject: [PATCH v2 2/3] mm, slub: don't combine pr_err with INFO
Date: Mon, 1 Feb 2021 19:56:09 +0800 [thread overview]
Message-ID: <20210201115610.87808-3-laoar.shao@gmail.com> (raw)
In-Reply-To: <20210201115610.87808-1-laoar.shao@gmail.com>
It is strange to combine "pr_err" with "INFO", so let's remove the
prefix completely.
This patch is motivated by David's comment[1].
- before the patch
[ 8846.517809] INFO: Slab 0x00000000f42a2c60 objects=33 used=3 fp=0x0000000060d32ca8 flags=0x17ffffc0010200(slab|head)
- after the patch
