Subject: linux-next: manual merge of the akpm-current tree with Linus' tree
Date: Mon, 23 Dec 2013 14:58:50 +1100 [thread overview]
Message-ID: <20131223145850.c07c0c869a999fa76a319853@canb.auug.org.au> (raw)
[-- Attachment #1: Type: text/plain, Size: 1914 bytes --]
Hi Andrew,
Today's linux-next merge of the akpm-current tree got conflicts in
include/linux/mm.h and mm/memory.c between commit 597d795a2a78 ("mm: do
not allocate page->ptl dynamically, if spinlock_t fits to long") from
the tree and commit 489bd4be2d70 ("mm: create a separate slab for
page->ptl allocation") from the akpm-current tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
