Subject: [PATCH 3.18 126/185] btrfs: fix lockdep splat in btrfs_alloc_subvolume_writers
Date: Mon, 28 May 2018 12:02:47 +0200 [thread overview]
Message-ID: <20180528100103.548714407@linuxfoundation.org> (raw)
In-Reply-To: <20180528100050.700971285@linuxfoundation.org>
3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jeff Mahoney <jeffm@suse.com>
[ Upstream commit 8a5a916d9a35e13576d79cc16e24611821b13e34 ]
While running btrfs/011, I hit the following lockdep splat.
This is the important bit:
pcpu_alloc+0x1ac/0x5e0
__percpu_counter_init+0x4e/0xb0
btrfs_init_fs_root+0x99/0x1c0 [btrfs]
btrfs_get_fs_root.part.54+0x5b/0x150 [btrfs]
resolve_indirect_refs+0x130/0x830 [btrfs]
find_parent_nodes+0x69e/0xff0 [btrfs]
btrfs_find_all_roots_safe+0xa0/0x110 [btrfs]
btrfs_find_all_roots+0x50/0x70 [btrfs]
btrfs_qgroup_prepare_account_extents+0x53/0x90 [btrfs]
btrfs_commit_transaction+0x3ce/0x9b0 [btrfs]
The percpu_counter_init call in btrfs_alloc_subvolume_writers
uses GFP_KERNEL, which we can't do during transaction commit.
This switches it to GFP_NOFS.
========================================================
WARNING: possible irq lock inversion dependency detected
4.12.14-kvmsmall #8 Tainted: G W
--------------------------------------------------------
kswapd0/50 just changed the state of lock:
(&delayed_node->mutex){+.+.-.}, at: [<ffffffffc06994fa>] __btrfs_release_delayed_node+0x3a/0x1f0 [btrfs]
but this lock took another, RECLAIM_FS-unsafe lock in the past:
(pcpu_alloc_mutex){+.+.+.}
and interrupts could create inverse lock ordering between them.
other info that might help us debug this:
Chain exists of:
&delayed_node->mutex --> &found->groups_sem --> pcpu_alloc_mutex
Possible interrupt unsafe locking scenario:
CPU0 CPU1

lock(pcpu_alloc_mutex);
