Subject: [PATCH 4.14 12/14] mm/page_owner.c: remove drain_all_pages from init_early_allocated_pages
Date: Thu, 30 Jul 2020 10:04:55 +0200 [thread overview]
Message-ID: <20200730074419.503737903@linuxfoundation.org> (raw)
In-Reply-To: <20200730074418.882736401@linuxfoundation.org>
From: Oscar Salvador <osalvador@techadventures.net>
commit 6bec6ad77fac3d29aed0d8e0b7526daedc964970 upstream.
When setting page_owner = on, the following warning can be seen in the
boot log:
WARNING: CPU: 0 PID: 0 at mm/page_alloc.c:2537 drain_all_pages+0x171/0x1a0
Modules linked in:
CPU: 0 PID: 0 Comm: swapper/0 Not tainted 4.15.0-rc7-next-20180109-1-default+ #7
Hardware name: Dell Inc. Latitude E7470/0T6HHJ, BIOS 1.11.3 11/09/2016
RIP: 0010:drain_all_pages+0x171/0x1a0
Call Trace:
init_page_owner+0x4e/0x260
start_kernel+0x3e6/0x4a6
? set_init_arg+0x55/0x55
secondary_startup_64+0xa5/0xb0
Code: c5 ed ff 89 df 48 c7 c6 20 3b 71 82 e8 f9 4b 52 00 3b 05 d7 0b f8 00 89 c3 72 d5 5b 5d 41 5
This warning is shown because we are calling drain_all_pages() in
init_early_allocated_pages(), but mm_percpu_wq is not up yet, it is being
set up later on in kernel_init_freeable() -> init_mm_internals().
