[PATCH v6 00/27] nfs: Mount API conversion

From: Scott Mayhew
Date: Tue Dec 10 2019 - 07:34:01 EST

Hi Anna, Trond,

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 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= 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


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
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: 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
NFS: Additional refactoring for fs_context conversion
NFS: Attach supplementary error information to fs_context.
