FYI, we noticed a +505 bytes kernel size regression due to commit:

commit: 2aded1a36e1d88a339a27013360fd0b335786ada (pid: Introduce pidfd_getfd syscall)
https://github.com/0day-ci/linux Sargun-Dhillon/Add-pidfd_getfd-syscall/20200104-192921

Details as below (size data is obtained by `nm --size-sort vmlinux`):
