Message-Id: <20180226185112.9657-1-thomas.de_schampheleire@nokia.com> Date: Mon, 26 Feb 2018 19:51:12 +0100 From: Thomas De Schampheleire <thomas.de_schampheleire@...ia.com> To: netdev@...r.kernel.org Cc: Thomas De Schampheleire <thomas.de_schampheleire@...ia.com> Subject: [PATCH iproute2] Fix compilation with kernel headers < 3.4 Since commit 596b1c94aa38e21b7a8c8562e8b61ccb744255d2, iproute2 uses types __kernel_long_t and __kernel_ulong_t but does not provide internal definitions for it. This means that compilation using kernel headers that are older than 3.4 (where these types were added) will fail. This situation may be uncommon for native compilation, but not uncommon for cross compilation where the toolchains may be a bit older. Provide the necessary types internally if not provided by the kernel headers to fix compilation in such cases.
