FYI, we noticed a +879 bytes kernel size regression due to commit:
commit: 9cfa950acecdd0c70e0d43d2e1c76dcf4797bb16 (fs: add mount_setattr())
https://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux.git mount_setattr
Details as below (size data is obtained by `nm --size-sort vmlinux`):
9573a242: namespace: only take read lock in do_reconfigure_mnt()
9cfa950a: fs: add mount_setattr()
