Subject: [PATCH 0/3] mm, memory_hotplug: fix few soft lockups in memory hotadd
Date: Mon, 18 Sep 2017 14:14:07 +0200 [thread overview]
Message-ID: <20170918121410.24466-1-mhocko@kernel.org> (raw)
Hi,
Johannes has noticed few soft lockups when adding a large nvdimm
device. All of them were caused by a long loop without any explicit
cond_resched which is a problem for !PREEMPT kernels. The fix is quite
straightforward. Just make sure that cond_resched gets called from time
to time.
Could you consider these for merging?
