I'm getting a warning in some ARM randconfig build:
WARNING: "ceph_monc_do_statfs" [fs/ceph/ceph.ko] has no CRC!
I have bisected this down to this particular commit fcd00b68bbe:

but I have no idea how the change relates to the symptom though.
What I see is that this one exported symbol has a __crc of a different
type from all the others:
$ nm net/ceph/mon_client.o | grep __crc
48c2e16e A __crc_ceph_monc_get_version
2360d633 A __crc_ceph_monc_get_version_async
0c50a10a A __crc_ceph_monc_got_map
w __crc_ceph_monc_do_statfs
b63e5cf5 A __crc_ceph_monc_init
c4602476 A __crc_ceph_monc_open_session
5e6fd15f A __crc_ceph_monc_renew_subs
53a9ed7f A __crc_ceph_monc_stop
33a329fa A __crc_ceph_monc_validate_auth
34010ef9 A __crc_ceph_monc_wait_osdmap
29c50846 A __crc_ceph_monc_want_map
I only see this in some rare randconfig builds and have not figured out
which options are required, but I have also been able to reproduce it on
an x86 config and have uploaded the .config file to
