From 6c1ea6dbf258cdf57367d9c979585a6a9fe5d091 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Wed, 26 Aug 2026 15:44:43 -0400 Subject: [PATCH] NFS: Import NFS3ERR definitions enum nfs_stat in uapi/linux/nfs.h collects the on-the-wire status codes for every NFS version under version-agnostic NFSERR_* names. The in-kernel NFS client and server reference these names internally, which drags uapi/linux/nfs.h into many translation units that need nothing else from that header. xdrgen conversion will provide spec-based definitions of the NFS status enum constants. Replacing the existing internal references with version-specific names requires a version-specific spelling for each code that NFSD uses. linux/nfs4.h already supplies the NFSv4 codes, but NFSv3 has no counterpart header, and not every NFSv3 code has an NFS4ERR_* spelling: NFSERR_NOT_SYNC (10002) and NFSERR_REMOTE (71) have no NFSv4 equivalent at all, and NFSERR_JUKEBOX (10008) appears in NFSv4 as NFS4ERR_DELAY. Introduce the NFSv3 status codes as NFS3ERR_* in linux/nfs3.h so a subsequent patch can respell NFSD's status definitions without relying on uapi/linux/nfs.h.
