Subject: [PATCH v2 01/11] mm/bootmem: drop duplicated kernel-doc comments
Date: Sat, 30 Jun 2018 17:54:56 +0300	[thread overview]
Message-ID: <1530370506-21751-2-git-send-email-rppt@linux.vnet.ibm.com> (raw)
In-Reply-To: <1530370506-21751-1-git-send-email-rppt@linux.vnet.ibm.com>

Parts of the bootmem interfaces are duplicated in nobootmem.c along with
the kernel-doc comments. There is no point to keep two copies of the
comments, so let's drop the bootmem.c copy.
