Merge branch 'lwt-module-unload'
Robert Shearman says: ==================== net: Fix oops on state free after lwt module unload An oops is seen in lwtstate_free after an lwt ops module has been unloaded. This patchset fixes this by preventing modules implementing lwtunnel ops from being unloaded whilst there's state alive using those ops. The first patch adds fills in a new owner field in all lwt ops and the second patch makes use of this to reference count the modules as state is built and destroyed using them. Changes in v3: - don't put module reference if try_module_get fails on building state Changes in v2: - specify module owner for all modules as suggested by DaveM - reference count all modules building lwt state, not just those ops implementing destroy_state, as also suggested by DaveM. - rebased on top of David Ahern's lwtunnel changes ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
