Subject[PATCH 05/30] sctp: Add missing annotation for sctp_transport_walk_start()
Date
Sparse reports a warning at sctp_transport_walk_start()

warning: context imbalance in sctp_transport_walk_start
- wrong count at exit

The root cause is the missing annotation at sctp_transport_walk_start()
Add the missing __acquires(RCU) annotation
