Subject: [PATCH v4 00/11] nfsd: implement the "delstid" draft
Sorry this has taken me a bit to re-post. I've been working on some
pynfs testcases for CB_GETATTR, and have found more bugs in our
implementation.
This repost is based on top of Chuck's nfsd-next branch. The first two
patches fix a couple of different bugs in how we handle the change attr.
I also dropped one of the patches from the last series that tried to
correct how we were handling the change attr. After going over RFC8881
section 10.4.3 a few times, I think the existing code in this respect is
actually correct. We advance the change attr in the inode on every
CB_GETATTR, which follows the guidance in the spec.
The rest of the series is more or less the same as the last one.

Changes in v4:
- get attrs from correct inode when issuing write deleg
- dropped some change attr handling patches that were incorrect
- only request FATTR4_CHANGE in CB_GETATTR if the file isn't modified
- Link to v3: https://lore.kernel.org/r/20240829-delstid-v3-0-271c60806c5d@kernel.org
Changes in v3:
- fix includes in nfs4xdr_gen.c
- drop ATTR_CTIME_DLG flag (just use ATTR_DELEG instead)
- proper handling for SETATTR (maybe? Outstanding q about stateid here)
- incorporate Neil's patches for handling non-delegation leases
- always return times from CB_GETATTR instead of from local vfs_getattr
- fix potential races vs. mgtimes by moving ctime handling into VFS layer
- Link to v2: https://lore.kernel.org/r/20240826-delstid-v2-0-e8ab5c0e39cc@kernel.org
Changes in v2:
- rebase onto Chuck's lkxdrgen branch, and reworked how autogenerated
code is included
- declare nfsd_open_arguments as a global, so it doesn't have to be
set up on the stack each time
- delegated timestamp support has been added
- Link to v1: https://lore.kernel.org/r/20240816-delstid-v1-0-c221c3dc14cd@kernel.org
