There are 3 remaining files without an extension inside the fs docs
dir.Manually convert them to ReST.
In the case of the nfs/exporting.rst file, as the nfs docs
aren't ported yet, I opted to convert and add a :orphan: there,
with should be removed when it gets added into a nfs-specific
part of the fs documentation.Signed-off-by: Mauro Carvalho Chehab

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.By default all files without license information are under the default
license of the kernel, which is GPL version 2.Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if

When nfsd calls fh_to_dentry, it expect ESTALE or ENOMEM as errors.
In particular it can be tempting to return ENOENT, but this is not
handled well by nfsd.Rather than requiring strict adherence to error code code filesystems,
treat all unexpected error codes the same as ESTALE. This is safest.Signed-off-by: NeilBrown

Add three methods to allow exporting pnfs block layout volumes:
- get_uuid: get a filesystem unique signature exposed to clients
- map_blocks: map and if nessecary allocate blocks for a layout
- commit_blocks: commit blocks in a layout once the client is done with themFor now we stick the external pnfs block layout interfaces into s_export_op to
avoid mixing them up with the internal interface between the NFS server and
the layout drivers. Once we've fully internalized the latter interface we
can redecide if these methods should stay in s_export_ops.Signed-off-by: Christoph Hellwig

Pull nfsd update from Bruce Fields:
"Included this time:- more nfsd containerization work from Stanislav Kinsbursky: we're
not quite there yet, but should be by 3.9.- NFSv4.1 progress: implementation of basic backchannel security
negotiation and the mandatory BACKCHANNEL_CTL operation. Seehttp://wiki.linux-nfs.org/wiki/index.php/Server_4.0_and_4.1_issues
for remaining TODO's
- Fixes for some bugs that could be triggered by unusual compounds.
Our xdr code wasn't designed with v4 compounds in mind, and it
shows. A more thorough rewrite is still a todo.- If you've ever seen "RPC: multiple fragments per record not
supported" logged while using some sort of odd userland NFS client,
that should now be fixed.- Further work from Jeff Layton on our mechanism for storing
information about NFSv4 clients across reboots.- Further work from Bryan Schumaker on his fault-injection mechanism
(which allows us to discard selective NFSv4 state, to excercise
rarely-taken recovery code paths in the client.)- The usual mix of miscellaneous bugs and cleanup.
Thanks to everyone who tested or contributed this cycle."

- Add commit_metadata export_operation to allow the underlying filesystem to
decide how to commit an inode most efficiently.- Usage of nfsd_sync_dir and write_inode_now has been replaced with the
commit_metadata function that takes a svc_fh.- The commit_metadata function calls the commit_metadata export_op if it's
there, or else falls back to sync_inode instead of fsync and write_inode_now
because only metadata need be synced here.- nfsd4_sync_rec_dir now uses vfs_fsync so that commit_metadata can be static

Add the guts for the new filesystem API to exportfs.
There's now a fh_to_dentry method that returns a dentry for the object looked
for given a filehandle fragment, and a fh_to_parent operation that returns the
dentry for the encoded parent directory in case the file handle contains it.There are default implementations for these methods that only take a callback
for an nfs-enhanced iget variant and implement the rest of the semantics.Signed-off-by: Christoph Hellwig

This patchset is a medium scale rewrite of the export operations interface.
The goal is to make the interface less complex, and easier to understand from
the filesystem side, aswell as preparing generic support for exporting of
64bit inode numbers.This touches all nfs exporting filesystems, and I've done testing on all of
the filesystems I have here locally (xfs, ext2, ext3, reiserfs, jfs)This patch:
Add a structured fid type so that we don't have to pass an array of u32 values
around everywhere. It's a union of possible layouts.As a start there's only the u32 array and the traditional 32bit inode format,
but there will be more in one of my next patchset when I start to document the
various filehandle formats we have in lowlevel filesystems better.Also add an enum that gives the various filehandle types human- readable
names.Note: Some people might think the struct containing an anonymous union is
ugly, but I didn't want to pass around a raw union type.Signed-off-by: Christoph Hellwig

Currently NFSD calls directly into filesystems through the export_operations
structure. I plan to change this interface in various ways in later patches,
and want to avoid the export of the default operations to NFSD, so this patch
adds two simple exportfs_encode_fh/exportfs_decode_fh helpers for NFSD to call
instead of poking into exportfs guts.Signed-off-by: Christoph Hellwig
