Merge branch 'devlink-unregister'
Jakub Kicinski says:
====================
devlink: remove the wait-for-references on unregister
Move the registration and unregistration of the devlink instances
under their instance locks. Don't perform the netdev-style wait
for all references when unregistering the instance.
Instead the devlink instance refcount will only ensure that
the memory of the instance is not freed. All places which acquire
access to devlink instances via a reference must check that the
instance is still registered under the instance lock.
This fixes the problem of the netdev code accessing devlink
instances before they are registered.
RFC: https://lore.kernel.org/all/20221217011953.152487-1-kuba@kernel.org/
- rewrite the cover letter
- rewrite the commit message for patch 1
- un-export and rename devl_is_alive
- squash the netdevsim patches
