[ Upstream commit af17092810a887178195276255b7b31f8fbe7dbe ] Instead of always multicasting responses, send a unicast netlink message directed at the correct pid. This will be needed if we ever want to support multiple userspace processes interacting with the kernel over iSCSI netlink simultaneously. Limitations can currently be seen if you attempt to run multiple iscsistart commands in parallel. We've fixed up the userspace issues in iscsistart that prevented multiple instances from running, so now attempts to speed up booting by bringing up multiple iscsi sessions at once in the initramfs are just running into misrouted responses that this fixes.

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.
