Note that there are a lot of preliminary patches, some from David and some from Al. The final patch (the one that does the actual conversion) from the David's initial posting has been split into 5 separate patches, and the entire set has been rebased on top of v5.5-rc1. Changes since v5: - fixed possible derefence of error pointer in nfs4_validate_fspath() reported by Dan Carpenter - rebased on top of v5.5-rc1 Changes since v4: - further split the original "NFS: Add fs_context support" patch (new patch is about 25% smaller than the v4 patch) - fixed NFSv4 referral mounts (broken in the original patch) - fixed leak of nfs_fattr when fs_context is freed Changes since v3: - changed license and copyright text in fs/nfs/fs_context.c Changes since v2: - fixed the conversion of the nconnect=3D option - added '#if IS_ENABLED(CONFIG_NFS_V4)' around nfs4_parse_monolithic() to avoid unused-function warning when compiling with v4 disabled Chagnes since v1: - split up patch 23 into 4 separate patches -Scott Al Viro (15): saner calling conventions for nfs_fs_mount_common() nfs: stash server into struct nfs_mount_info nfs: lift setting mount_info from nfs4_remote{,_referral}_mount nfs: fold nfs4_remote_fs_type and nfs4_remote_referral_fs_type nfs: don't bother setting/restoring export_path around do_nfs_root_mount() nfs4: fold nfs_do_root_mount/nfs_follow_remote_path nfs: lift setting mount_info from nfs_xdev_mount() nfs: stash nfs_subversion reference into nfs_mount_info nfs: don't bother passing nfs_subversion to ->try_mount() and nfs_fs_mount_common() nfs: merge xdev and remote file_system_type nfs: unexport nfs_fs_mount_common() nfs: don't pass nfs_subversion to ->create_server() nfs: get rid of mount_info ->fill_super() nfs_clone_sb_security(): simplify the check for server bogosity nfs: get rid of ->set_security() David Howells (8): NFS: Move mount parameterisation bits into their own file NFS: Constify mount argument match tables NFS: Rename struct nfs_parsed_mount_data to struct nfs_fs_context NFS: Split nfs_parse_mount_options() NFS: Deindent nfs_fs_context_parse_option() NFS: Add a small buffer in nfs_fs_context to avoid string dup NFS: Do some tidying of the parsing code NFS: Add fs_context support. Scott Mayhew (4): NFS: rename nfs_fs_context pointer arg in a few functions NFS: Convert mount option parsing to use functionality from fs_parser.h NFS: Additional refactoring for fs_context conversion NFS: Attach supplementary error information to fs_context. fs/nfs/Makefile | 2 +- fs/nfs/client.c | 80 +- fs/nfs/fs_context.c | 1424 +++++++++++++++++++++++++ fs/nfs/fscache.c | 2 +- fs/nfs/getroot.c | 73 +- fs/nfs/internal.h | 132 +-- fs/nfs/namespace.c | 146 ++- fs/nfs/nfs3_fs.h | 2 +- fs/nfs/nfs3client.c | 6 +- fs/nfs/nfs3proc.c | 2 +- fs/nfs/nfs4_fs.h | 9 +- fs/nfs/nfs4client.c | 99 +- fs/nfs/nfs4file.c | 1 + fs/nfs/nfs4namespace.c | 292 +++--- fs/nfs/nfs4proc.c | 2 +- fs/nfs/nfs4super.c | 257 ++--- fs/nfs/proc.c | 2 +- fs/nfs/super.c | 2217 +++++---------------------------------- include/linux/nfs_xdr.h | 9 +- 19 files changed, 2287 insertions(+), 2470 deletions(-) create mode 100644 fs/nfs/fs_context.c --=20 2.17.2
