Subject: [PATCH v4 07/15] btrfs: Implement set_extent_bits_nowait
Date: Wed, 27 Mar 2019 14:24:10 +0200	[thread overview]
Message-ID: <20190327122418.24027-8-nborisov@suse.com> (raw)
In-Reply-To: <20190327122418.24027-1-nborisov@suse.com>

It will be used in a future patch that will require modifying an
extent_io_tree struct under a spinlock.
