From 36ffa3d0de54c1cf516ea32a5ec556f5c9874795 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 29 Jul 2024 11:47:23 +1000 Subject: nfsd: be more systematic about selecting error codes for internal use. Rather than using ad hoc values for internal errors (30000, 11000, ...) use 'enum' to sequentially allocate numbers starting from the first known available number - now visible as NFS4ERR_FIRST_FREE. The goal is values that are distinct from all be32 error codes. To get those we must first select integers that are not already used, then convert them with cpu_to_be32().
