treewide: remove editor modelines and cruft

The section "19) Editor modelines and other cruft" in
Documentation/process/coding-style.rst clearly says, "Do not include any
of these in source files."

I recently receive a patch to explicitly add a new one.

Let's do treewide cleanups, otherwise some people follow the existing code
and attempt to upstream their favoriate editor setups.

It is even nicer if scripts/checkpatch.pl can check it.

If we like to impose coding style in an editor-independent manner, I think
editorconfig (patch [1]) is a saner solution.

Puyll NFS client updates from Anna Schumaker:
"Stable bugfixes:
- Fix memory leaks and corruption in readdir # v2.6.37+
- Directory page cache needs to be locked when read # v2.6.37+

New features:
- Convert NFS to use the new mount API
- Add "softreval" mount option to let clients use cache if server goes down
- Add a config option to compile without UDP support
- Limit the number of inactive delegations the client can cache at once
- Improved readdir concurrency using iterate_shared()

Other bugfixes and cleanups:
- More 64-bit time conversions
- Add additional diagnostic tracepoints
- Check for holes in swapfiles, and add dependency on CONFIG_SWAP
- Various xprtrdma cleanups to prepare for 5.7's changes
- Several fixes for NFS writeback and commit handling
- Fix acls over krb5i/krb5p mounts
- Recover from premature loss of openstateids
- Fix NFS v3 chacl and chmod bug
- Compare creds using cred_fscmp()
- Use kmemdup_nul() in more places
- Optimize readdir cache page invalidation
- Lease renewal and recovery fixes"

NFSv4.0: nfs4_do_fsinfo() should not do implicit lease renewals

Currently, each time nfs4_do_fsinfo() is called it will do an implicit
NFS4 lease renewal, which is not compliant with the NFS4 specification.
This can result in a lease being expired by an NFS server.

Commit 83ca7f5ab31f ("NFS: Avoid PUTROOTFH when managing leases")
introduced implicit client lease renewal in nfs4_do_fsinfo(),
which can result in the NFSv4.0 lease to expire on a server side,
and servers returning NFS4ERR_EXPIRED or NFS4ERR_STALE_CLIENTID.

This can easily be reproduced by frequently unmounting a sub-mount,
then stat'ing it to get it mounted again, which will delay or even
completely prevent client from sending RENEW operations if no other
NFS operations are issued. Eventually nfs server will expire client's
lease and return an error on file access or next RENEW.

This can also happen when a sub-mount is automatically unmounted
due to inactivity (after nfs_mountpoint_expiry_timeout), then it is
mounted again via stat(). This can result in a short window during
which client's lease will expire on a server but not on a client.
This specific case was observed on production systems.

This patch removes the implicit lease renewal from nfs4_do_fsinfo().
