Subject: [PATCH RFC v2 0/4] some fixes and clean up for mempolicy
Date: Fri, 27 Oct 2017 18:14:21 +0800 [thread overview]
Message-ID: <1509099265-30868-1-git-send-email-xieyisheng1@huawei.com> (raw)
This patchset is triggered by Xiojun's report of ltp test fail[1],
and I have sent a patch to resolve it by check nodes_empty of new_nodes[2].
The new version is to follow Vlastimil's suggestion, which fix by checking
the new_nodes value in function get_nodes. And I just split them to small
patches for easy to review and discussion. For more detail, please look
into each patches.
Change logs of v2:
* fix get_nodes's mask miscalculation
* remove redundant check in get_nodes
* fix the check of nodemask from user - per Vlastimil
Any comment and complain is welome.
Thanks
Yisheng Xie
