From: Xiangyu Chen <[email protected]> Hi Bruce,
When we enable the kernel debug feature "CONFIG_DEBUG_INFO_BTF", some modules would report "failed to validate module [XXXmodule] BTF: -22" error". The config CONFIG_MODULE_ALLOW_BTF_MISMATCH[1] can ignore it but the error message still can be found in kernel log. There is a commit has already fixed it[2] on master, so please help to merge the following commit from kernel master to linux-yocto v6.1, thanks. 9cb61e50bf6bf54db712bba6cf20badca4383f96 bpf: btf: limit logging of ignored BTF mismatches This issue was found on x86-64 platform, but since BTF is a common kernel feature, so please apply the commit on all 6.1 branches, thanks.
