From e344a031a4928e9f0ae3124f0e45e953a873f3bd Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Thu, 20 Nov 2025 15:15:51 -0500 Subject: [PATCH] NFSD: Add instructions on how to deal with xdrgen files xdrgen requires a number of Python packages on the build system. We don't want to add these to the kernel build dependency list, which is long enough already. The generated files are generated manually using $ cd fs/nfsd && make xdrgen whenever the .x files are modified, then they are checked into the kernel repo so others do not need to rebuild them.
