This all looks great to me. I really support autogenerating our XDR boilerplate, particularly as I've been looking at implementing CB_NOTIFY (which would be quite tedious to roll by hand). This would make it a lot simpler and less error prone. Do you have these patches in a branch in your tree that I could pick from?

However, do you need it rebased on nfsd-next? I can do that today if so. -- Chuck Lever
From: Chuck Lever <chuck.lever@oracle.com> For a description of this work-in-progress, see the new README file. For unfinished work items, ditto. The first patch adds the tool. The second patch is an nfs4_1.x file that I created to confirm that the tool indeed works for Jeff's purposes. Actual generated header and source are in fs/nfsd/nfs4xdr_gen.? . Feel free to ignore 2/2. It is included here only to demonstrate the tool's new "pragma" directives that I think can avoid the need to hand-edit generated source, as discussed in an earlier thread. Grep the new README or nfs4_1.x for "pragma". These patches apply to v6.11-rc4, but can be rebased on nfsd-next if they are found merge-worthy. See also: https://git.kernel.org/pub/scm/linux/kernel/git/cel/linux.git/log/?h=lkxdrgen For review, note that the numerous .j2 files are all tiny and can be skimmed in favor of the .py files, where the tool's logic is. All Python-related advice and guidance is gratefully accepted. -- Chuck Lever (2): tools: Add xdrgen NFSD: Create an initial nfs4_1.x file fs/nfsd/nfs4_1.x | 164 +++++++ fs/nfsd/nfs4xdr_gen.c | 236
