Events will be added to defer_q list when setting ha->status to SAS_HA_DRAINING. Events will be called after drain workqueue. Those events are added to the head of list, but they are scanned one by one from the head to the tail, which will cause those events be called in the reverse order of being added. So change list_add to list_add_tail in function sas_queue_work.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
