This cover email is intended for including my test results. This patch adds the ops table in nfs_common for knfsd to access NFS client modules without calling these functions directly. The client module registers their functions and deregisters them when the module is loaded and unloaded respectively. fs/nfs/nfs4file.c | 44 ++++++++++++-- fs/nfs/nfs4super.c | 6 ++ fs/nfs/super.c | 20 +++++++ fs/nfs_common/Makefile | 1 + fs/nfs_common/nfs_ssc.c | 136 +++++++++++++++++++++++++++++++++++++++++++ fs/nfsd/Kconfig | 2 +- fs/nfsd/nfs4proc.c | 3 +- include/linux/nfs_ssc.h | 77 ++++++++++++++++++++++++ 8 files changed, 281 insertions(+), 8 deletions(-) Test Results: Upstream version used for testing: 5.9-rc5 |----------------------------------------------------------| | NFSD | NFS_FS | NFS_V4 | RESULTS | |----------------------------------------------------------| | m | y | m | inter server copy OK | |----------------------------------------------------------| | m | m | m | inter server copy OK | |----------------------------------------------------------| | m | m | y (m) | inter server copy OK | |----------------------------------------------------------| | m | y | y | inter server copy OK | |----------------------------------------------------------| | m | n | n | NFS4ERR_STALE error | |----------------------------------------------------------| |----------------------------------------------------------| | NFSD | NFS_FS | NFS_V4 | RESULTS | |----------------------------------------------------------| | y | y | m | inter server copy OK | |----------------------------------------------------------| | y | m | m | inter server copy OK | |----------------------------------------------------------| | y | m | y (m) | inter server copy OK | |----------------------------------------------------------| | y | y | y | inter server copy OK | |----------------------------------------------------------| | y | n | n | NFS4ERR_STALE error | |----------------------------------------------------------| NOTE: When NFS_V4=y and NFS_FS=m, the build process automatically builds with NFS_V4=m and ignores the setting NFS_V4=y in the config file. This probably due to NFS_V4 in fs/nfs/Kconfig is configured to depend on NFS_FS.
