Remove references to private kernel header and defines from exported ib_user_verb.h file. The code snippet below is used to reproduce the issue: #include <stdio.h> #include <rdma/ib_user_verb.h> int main(void) { printf("IB_USER_VERBS_ABI_VERSION = %d\n", IB_USER_VERBS_ABI_VERSION); return 0; } It fails during compilation phase with an error: ➜ /tmp gcc main.c main.c:2:31: fatal error: rdma/ib_user_verb.h: No such file or directory #include <rdma/ib_user_verb.h> ^ compilation terminated. Fixes: 189aba99e700 ("IB/uverbs: Extend modify_qp and support packet pacing") CC: Bodong Wang <bodong@mellanox.com> CC: Matan Barak <matanb@mellanox.com> CC: Christoph Hellwig <hch@infradead.org> Tested-by: Slava Shwartsman <slavash@mellanox.com> Signed-off-by: Leon Romanovsky <leon@kernel.org> Signed-off-by: Doug Ledford <dledford@redhat.com>
