It looks like a problem in the header files due to the creds patches that just
went in:
a6babf4cbeaa (tag: kernel-6.14-rc1.cred, vfs/kernel-6.14.cred) cred: fold get_new_cred_many() into get_cred_many()
6efbb80490a5 cred: remove unused get_new_cred()
51c0bcf0973a tree-wide: s/revert_creds_light()/revert_creds()/g
6771e004b409 tree-wide: s/override_creds_light()/override_creds()/g
a51a1d6bcaa3 cred: remove old {override,revert}_creds() helpers
95c54bc81791 cred: return old creds from revert_creds_light()
0a670e151a71 tree-wide: s/override_creds()/override_creds_light(get_new_cred())/g
49dffdfde462 cred: Add a light version of override/revert_creds()
I don't any warnings though. Are you using gcc or clang?
