Howdy,
It looks like ceph_fs.h contains the mask flags (e.g. CEPH_SETATTR_MODE) used in ceph_setattr, but I do not see these flags in any header installed from .deb files (grep /usr/include/*).
Am I missing a location? Should these flags be part of the installed headers?
Thanks,
-Noah

You're right, those flags are only specified in ceph_fs.h. I don't
think it's appropriate to include that file in user-facing stuff as
it's mostly things that I'd consider to be Ceph internals, but the
CEPH_SETATTR_* stuff is obviously public since you need them for
ceph_setattr. My inclination would be to either move or duplicate them
into a header that's already installed, but I'm not sure which one is
best for that. Do you have any thoughts as a user? :)

java-libcephfs has a build dependency on libcephfs-dev deb that only contains libcephfs.h. These flags must be available during build and it seems to make little sense to add another header just for these bits. So as far as moving vs copying I'm not sure, but exposing all of ceph_fs.h seems like overkill. Related: does Ceph re-use the POSIX bit masks for mode_t?

The simplest thing is to probably duplicate them (with an #ifndef guard)
in libcephfs.h. I'll push something to do that now.

Yep!
