[2/3] RDMA/rxe: Remove the common is_user member of struct rxe_qp

Commit Message

Xiao Yang Aug. 23, 2021, 9:22 a.m. UTC

The following commit introduced separate is_user members for struct
rxe_sq/rxe_rq/rxe_srq but no code uses the separate is_user member
of struct rxe_sq and lots of code still use the common is_user member
of struct rxe_qp.  So it is clear to make all code use separate is_user
members uniformly and remove the common is_user member.

Fixes: 5bcf5a59c41e ("RDMA/rxe: Protext kernel index from user space")
