Kirill Tkhai says: ==================== Make pernet_operations always read locked All the pernet_operations are converted, and the last one is in this patchset (nfsd_net_ops acked by J. Bruce Fields). So, it's the time to kill pernet_operations::async field, and make setup_net() and cleanup_net() always require the rwsem only read locked. All further pernet_operations have to be developed to fit this rule. Some of previous patches added a comment to struct pernet_operations about that. Also, this patchset renames net_sem to pernet_ops_rwsem to make the target area of the rwsem is more clear visible, and adds more comments. ==================== Signed-off-by: David S.

README
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.
