Subject: [PATCH 0/2] block: Fix deadlock when merging requests with BFQ
Date: Fri, 21 May 2021 00:33:51 +0200	[thread overview]
Message-ID: <20210520223353.11561-1-jack@suse.cz> (raw)

Hello,

This patch series fixes a lockdep complaint and a possible deadlock that
can happen when blk_mq_sched_try_insert_merge() merges and frees a request.
