There are many users/companies using older versions of compilers, kernels and everything. GCC <= 4.9 will still be used/supported (by third parties) for a handful of years at least. However, the important question is whether those users/companies care about running the latest kernels. Many of those definitely do not want to touch their kernel either. For those that do, there are several longterms to pick from that still support 4.9, as well as other workarounds. Thus I am usually in favor of raising the minimum whenever new hacks are required to be added. On the other hand, we already raised the version twice this year and it is not clear to me what is the minimum version we would need to go for to ensure this does not bite us. > If this is a real problem with GCC version <= 5, so can this be moved > to a GCC specific include header-file? > Thinking of include/linux/compiler-gcc.h or > include/linux/compiler_types.h with a GCC-VERSION check? That would be better if it can be done, yes. Cheers, Miguel
