Subject: Re: [RFC][PATCH v2 0/2] Improve libsas hotplug

Hi James, sorry to bother you, these two patches try to fix several issues
in libsas, Dan Williams and John Garry also found similar issue, and post
some patches before. Dan Williams's solution fix the sysfs warning calltrace,
but may introduce new flutter issue.

In these two patches, we introduce a new workqueue to fix the flutter issue.
Do you have time to look at these patches ? Your comments is important to us,
It help us to know whether we are in the right direction to fix these issues.

Thanks!
Yijing.
