[PATCH v5 03/10] nfsd: switch to autogenerated definitions for open_delegation_type4

Jeff Layton
2024-12-09T21:14:19Z

Rename the enum with the same name in include/linux/nfs4.h, add the
proper enum to nfs4_1.x and regenerate the headers and source files. Do
a mass rename of all NFS4_OPEN_DELEGATE_* to OPEN_DELEGATE_* in the nfsd
directory.
