David, where can I find the git branch this patch was applied to? I don't see it anywhere in security-keys or linux-security. I recently added KEYS_COMPAT to arm64 (5c2a625937ba); that should be reverted after this patch. Also, I'd like to submit a follow-on patch that removes KEYS_COMPAT and simply uses COMPAT. And the parisc architecture doesn't use compat_sys_keyctl() in its compat syscall table, so that should be fixed too (though that's not a new bug). - Eric
