Jiri Pirko 30bab7cdb5 net: devlink: make sure that devlink_try_get() works with valid pointer during xarray iteration ... Remove dependency on devlink_mutex during devlinks xarray iteration. The reason is that devlink_register/unregister() functions taking devlink_mutex would deadlock during devlink reload operation of devlink instance which registers/unregisters nested devlink instances. The devlinks xarray consistency is ensured internally by xarray. There is a reference taken when working with devlink using devlink_try_get(). But there is no guarantee that devlink pointer picked during xarray iteration is not freed before devlink_try_get() is called. Make sure that devlink_try_get() works with valid pointer. Achieve it by: 1) Splitting devlink_put() so the completion is sent only after grace period. Completion unblocks the devlink_unregister() routine, which is followed-up by devlink_free() 2) During devlinks xa_array iteration, get devlink pointer from xa_array holding RCU read lock and taking reference using devlink_try_get() before unlock.
