Commit Message

Alexander Lobakin April 21, 2022, 12:39 a.m. UTC
Some standard C library implementations, e.g. Musl, ship the UAPI
definitions themselves to not be dependent on the UAPI headers and
their versions. Their kernel UAPI counterparts are usually guarded
with some definitions which the formers set in order to avoid
duplicate definitions.
In such cases, include order matters. Change it in two samples: in
the first, kernel UAPI ioctl definitions should go before the libc
ones, and the opposite story with the second, where the kernel
includes should go later to avoid struct redefinitions.

Fixes: b4b8faa1ded7 ("samples/bpf: sample application and documentation for AF_XDP sockets")
Fixes: e55190f26f92 ("samples/bpf: Fix build for task_fd_query_user.c")
