Hi Anna, Here's a set of patches that converts NFS to use the mount API. 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 4 separate patches, and the entire set has been rebased on top of v5.3-rc6. Changes since v2: - fixed the conversion of the nconnect= option - added '#if IS_ENABLED(CONFIG_NFS_V4)' around nfs4_parse_monolithic() to avoid unused-function warning when compiling with v4 disabled -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.
