Subject: [PATCH 4.4 03/74] Btrfs: fix deadlock running delayed iputs at transaction commit time
Date: Mon, 7 Mar 2016 16:02:28 -0800 [thread overview]
Message-ID: <20160308000315.405146736@linuxfoundation.org> (raw)
In-Reply-To: <20160308000315.294406921@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Filipe Manana <fdmanana@suse.com>
commit c2d6cb1636d235257086f939a8194ef0bf93af6e upstream.
While running a stress test I ran into a deadlock when running the delayed
iputs at transaction time, which produced the following report and trace:

This happens because we can recursively acquire the semaphore
fs_info->delayed_iput_sem when attempting to allocate space to satisfy
a file write request as shown in the first trace above - when committing
a transaction we acquire (down_read) the semaphore before running the
delayed iputs, and when running a delayed iput() we can end up calling
an inode's eviction handler, which in turn commits another transaction
and attempts to acquire (down_read) again the semaphore to run more
delayed iput operations.
This results in a deadlock because if a task acquires multiple times a
semaphore it should invoke down_read_nested() with a different lockdep
class for each level of recursion.
Fix this by simplifying the implementation and use a mutex instead that
is acquired by the cleaner kthread before it runs the delayed iputs
instead of always acquiring a semaphore before delayed references are
run from anywhere.
