unlock_native_capacity is never called from check_disk_change(), and
while revalidate_disk can be called from it, it can also be called
from two other places at the moment.Signed-off-by: Christoph Hellwig

Pull documentation updates from Jonathan Corbet:
"It's been a busy cycle for documentation - hopefully the busiest for a
while to come. Changes include:- Some new Chinese translations
- Progress on the battle against double words words and non-HTTPS
URLs- Some block-mq documentation
- More RST conversions from Mauro. At this point, that task is
essentially complete, so we shouldn't see this kind of churn again
for a while. Unless we decide to switch to asciidoc or
something...:)- Lots of typo fixes, warning fixes, and more"

This replaces ->readpages with a saner interface:
- Return void instead of an ignored error code.
- Page cache is already populated with locked pages when ->readahead
is called.
- New arguments can be passed to the implementation without changing
all the filesystems that use a common helper function like
mpage_readahead().Signed-off-by: Matthew Wilcox (Oracle)

We currently revoke read delegations on any write open or any operation
that modifies file data or metadata (including rename, link, and
unlink). But if the delegation in question is the only read delegation
and is held by the client performing the operation, that's not really
necessary.It's not always possible to prevent this in the NFSv4.0 case, because
there's not always a way to determine which client an NFSv4.0 delegation
came from. (In theory we could try to guess this from the transport
layer, e.g., by assuming all traffic on a given TCP connection comes
from the same client. But that's not really correct.)In the NFSv4.1 case the session layer always tells us the client.
This patch should remove such self-conflicts in all cases where we can
reliably determine the client from the compound.To do that we need to track "who" is performing a given (possibly
lease-breaking) file operation. We're doing that by storing the
information in the svc_rqst and using kthread_data() to map the current
task back to a svc_rqst.Signed-off-by: J. Bruce Fields

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
