I think the expectation is that everything in STATX_BASIC_MASK is always returned to allow equivalence between stat() and statx(). So requesting STATX_CTIME separately from STATX_MTIME isn't implemented widely, maybe even not at atll?, yet.

The bigger issue here is that it's not setting the ctime and mtime fields while leaving the STATX_CTIME and STATX_MTIME flags set. I'll plan to fix that up in some fashion in the next post.

Probably we ought to be more selective with how the result_mask gets set in vfs_getattr_nosec. Applications that use statx() effectively are still pretty rare, so most calls will fetch both times anyway.

When the mtime or ctime is being queried via getattr, ensure that we mark the inode for a high-res timestamp update on the next pass. Also, switch to current_cmtime for other c/mtime updates. With this change, we're better off having the NFS server just ignore the i_version field and have it use the ctime instead, so clear the STATX_CHANGE_COOKIE flag in the result mask in ->getattr.
