[PATCHv2 1/1] RDMA/rxe: Fix qp error handler

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Zhu Yanjun <yanjun.zhu@xxxxxxxxx>

About 7 spin locks in qp creation needs to be initialized. Now these
spin locks are initialized in the function rxe_qp_init_misc. This
will avoid the error "initialize spin locks before use".
