From: Leon Romanovsky <leonro@xxxxxxxxxx>
The ceph_features.h has declaration of features that are not in-use
in kernel code. This causes to seeing such compilation warnings in
almost every kernel compilation.
./include/linux/ceph/ceph_features.h:14:24: warning: 'CEPH_FEATURE_UID' defined but not used [-Wunused-const-variable=]
14 | static const uint64_t CEPH_FEATURE_##name = (1ULL<<bit); \
| ^~~~~~~~~~~~~
./include/linux/ceph/ceph_features.h:75:1: note: in expansion of macro 'DEFINE_CEPH_FEATURE'
75 | DEFINE_CEPH_FEATURE( 0, 1, UID)
| ^~~~~~~~~~~~~~~~~~~
The upstream kernel indeed doesn't have any use of them, so delete it.

I'm sending this as RFC because probably the patch is wrong, but I
would like to bring your attention to the existing problem and asking
for an acceptable solution.
