Out of curiosity - how much PITA would it be to put request_mask into kstat? Set it in vfs_getattr_nosec() (and those get_file_..._info() on smbd side) and don't bother with that kind of propagation boilerplate - just have generic_fillattr() pick it there...

It could be done. To do that right, I think we'd want to drop request_mask from the ->getattr prototype as well and just have everything use the mask in the kstat. I don't think it'd reduce the size of the patchset in any meaningful way, but it might make for a more sensible API over the long haul.

What I suggest is branchpoint -> field addition (trivial commit) -> argument removal | V your series, starting with "use stat->request_mask in generic_fillattr()" Total size would be about the same, but it would be easier to follow the less trivial part of that. Nothing in your branch downstream of that touches any ->getattr() instances, so it should have no conflicts with the argument removal side of things.

The only problem with this plan is that Linus has already merged this. I've no issue with adding the request_mask to the kstat and removing it as a separate parameter elsewhere, but I think we'll need to do it on top of what's already been merged.

D'oh... My apologies; I'll do a branch on top of that (and rebase on top of -rc1 once the window closes).

generic_fillattr just fills in the entire stat struct indiscriminately today, copying data from the inode. There is at least one attribute (STATX_CHANGE_COOKIE) that can have side effects when it is reported, and we're looking at adding more with the addition of multigrain timestamps. Add a request_mask argument to generic_fillattr and have most callers just pass in the value that is passed to getattr. Have other callers (e.g. ksmbd) just pass in STATX_BASIC_STATS. Also move the setting of STATX_CHANGE_COOKIE into generic_fillattr.
