hi, new version of pahole (1.24) is causing compilation fail for 5.15 stable kernel, discussed in here [1][2]. Sending fix for that plus one dependency patch.
Note for patch 1: there was one extra line change in scripts/pahole-flags.sh file in its linux tree merge commit:
fc02cb2b37fe Merge tag 'net-next-for-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
not sure how/if to track that, I squashed the change in.
Squashing is fine, thanks.
And do we also need this for kernels older than 5.15? Like 5.10 and 5.4?
yes, 5.10 needs similar patchset, but this for 5.15 won't apply there, so I'll send it separately
5.4 passes compilation, but I don't think it will boot properly, still need to check on that
in any case, more patches are coming ;-)
Ok, these two are now queued up, feel free to send the rest when you have them ready.
hi, as for 5.10 changes, I have them ready, pushed in here: git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git pahole_fix_5_10
but it looks like CONFIG_DEBUG_INFO_BTF is not being used in 5.10, because I had to backport other similar option, that would break the build even earlier (--skip_encoding_btf_vars), or people use just old pahole ;-)
I suggest we wait with this change until somebody actually wants this fixed, AFAICS there's no report of broken 5.10 build yet
thanks, jirka
