Created attachment 908810 [details] build.log.xz build log and emerge --info (compressed because it exceeds attachment limit, use 'xzless' to read it)
Found the following implicit function declarations in configure logs: config.log:4378 - __vfs_write config.log:4653 - PageFsMisc config.log:4791 - current_kernel_time config.log:4957 - do_sync_read config.log:5107 - find_task_by_pid config.log:5229 - generic_file_aio_read config.log:5536 - inode_setattr config.log:5677 - kernel_setsockopt config.log:5864 - page_follow_link config.log:6025 - __pagevec_lru_add_file config.log:6157 - path_lookup config.log:6786 - default_file_splice_read config.log:7013 - lru_cache_add_file config.log:7276 - wrap_directory_iterator config.log:7442 - inode_set_atime config.log:7446 - inode_set_mtime config.log:8646 - inode_setattr config.log:10958 - get_sb_nodev config.log:11140 - refrigerator config.log:22351 - bswap16 config.log:22686 - bswap32
They are artifacts of autoconf testing for various Linux kernel functions at different kernel versions.

Just be aware that this will be a very long and changing list. The configure tests are looking for various functions that may or may not exist not only in Linux but all the other platforms that openafs supports. It will take me a while to dig through all the autoconf tests to come up with the list that will handle this properly.
I have a solution for this. It will probably be a gentoo specific change (I'm not sure if upstream will take the change). What the core issue is, is that the upstream build process captures the output from the compile, does a check then sends the output to the log. The implicit function declarations are expected -- since it is what upstream is explicitly testing for. My solution is to simply filter the output from the compile to remove the line that contains the warning for the function that is being tested for (e.g. if the test is for foo and foo shows up as an implicit declaration, we can ignore it. However if the test is for foo and bar shows up as an implicit declaration, then that should be flagged. There is a new release for openafs (1.8.13.1) that contains support for linux 6.12. I will include my fix when I submit a new ebuild.
(In reply to Cheyenne Wills from comment #7) We can set QA_CONFIG_IMPL_DECL_SKIP (an array of functions to be ignored, or you can do a wildcard) in the ebuild with a comment explaining the situation.

Ah.. didn't know about using a wildcard. That might be the easier route. Upstream does pay close attention to the output of configure, and within the overall build upstream uses -Wall -Werror for checking the builds.
