RDS: Rewrite connection cleanup, fixing oops on rmmod
This fixes a bug where a connection was unexpectedly not on *any* list while being destroyed. It also cleans up some code duplication and regularizes some function names. * Grab appropriate lock in conn_free() and explain in comment * Ensure via locking that a conn is never not on either a dev's list or the nodev list * Add rds_xx_remove_conn() to match rds_xx_add_conn() * Make rds_xx_add_conn() return void * Rename remove_{,nodev_}conns() to destroy_{,nodev_}conns() and unify their implementation in a helper function * Document lock ordering as nodev conn_lock before dev_conn_lock Reported-by: Yosef Etigin <yosefe@voltaire.com> Signed-off-by: Andy Grover <andy.grover@oracle.com> Signed-off-by: David S.
