Posting as an RFC set as this should not be merged until the libcephfs
interfaces are in place.
This patchset should give the samba vfs ceph module support for a
real "birthtime" on files. It relies on a set of new interfaces
being added to ceph in this pull request:
https://github.com/ceph/ceph/pull/10922
While that's being reviewed, I'd like to also put this set of patches
out here to get some eyes on them. Does the new ceph_statx() interface
seem ok? (Note that my ulterior motive here is to use this as a PoC that
we can point at for a similar kernel system call).
Note that while the set should be bisectable, birthtime handling may be
"iffy" in some of the interim points of the set, due to different calls
fetching and setting it in different places. The end result should be
consistent though.
I've also not given much thought to preserving birthtimes on "legacy"
ceph filesystems that don't have this support but that may have had it
set in the xattr. Opinions are welcome there. Should we try to do that
somehow?
