FYI, we noticed a +4007 bytes kernel size regression due to commit:
commit: 3389d7a0a4d77044d7a575f009d07cd6dc48452f (iov_iter: Add ITER_MAPPING)
https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git fscache-iter
Details as below (size data is obtained by `nm --size-sort vmlinux`):
1bcfb218: fscache: Remove the I/O operation manager
3389d7a0: iov_iter: Add ITER_MAPPING
