Hello Jianchao,

I think that Ming Lei's patch +ACI-blk-mq: remove synchronize+AF8-rcu() from
blk+AF8-mq+AF8-del+AF8-queue+AF8-tag+AF8-set()+ACI- makes Roman's patch superfluous. When I reposted
Roman's patch I had not yet noticed that Ming's patch is already in Jens'
tree. See also https://www.mail-archive.com/linux-block+AEA-vger.kernel.org/msg22956.html.
