Our CI built linux-stable-rc.git queue/6.1 at commit eef4a8a45ba1 ("btrfs: output the reason for open_ctree() failure"). (built for arm and arm64, albeit I don't think it matters.)
Building perf produced 2 build errors which I wanted to report even before the RC1 is out.
| ...tools/perf/util/namespaces.c:247:27: error: invalid type argument of '->' (have 'int') | 247 | RC_CHK_ACCESS(nsi)->in_pidns = true; | | ^~
introduced by commit 93520bacf784 ("perf namespaces: Introduce nsinfo__set_in_pidns()"). The RC_CK_ACCSS macro was introduced in 6.4. Removing the macro made this go away ( nsi->in_pidns = true; ).
Second perf build error: | ld: ...tools/perf/util/machine.c:1176: undefined reference to `kallsyms__get_symbol_start'
Introduced by commits: 710c2e913aa9 perf machine: Don't ignore _etext when not a text symbol 69a87a32f5cd perf machine: Include data symbols in the kernel map
These two use the function kallsyms__get_symbol_start added with: f9dd531c5b82 perf symbols: Add kallsyms__get_symbol_start() So f9dd531c5b82 would additionally be needed.
The kernel itself built fine, due to the perf error we don't have runtime testresults.
Best regards Max
