Fix up trivial conflicts (other header files, and removal of the ab3550 mfd driver) in
- drivers/media/dvb/frontends/dibx000_common.c
- drivers/media/video/{mt9m111.c,ov6650.c}
- drivers/mfd/ab3550-core.c
- include/linux/dmaengine.h
Some files were using the complete module.h infrastructure without
actually including the header at all. Fix them up in advance so
once the implicit presence is removed, we won't get failures like this:

These files were getting <linux/module.h> via an implicit include
path, but we want to crush those out of existence since they cost
time during compiles of processing thousands of lines of headers
for no reason. Give them the lightweight header that just contains
the EXPORT_SYMBOL infrastructure.

CLAIM_DELEGATE_CUR" was a temporary workaround for a problem fixed

If we create the object and then return failure to the client, we're
left with an unexpected file in the filesystem.
I'm trying to eliminate such cases but not 100% sure I have so an
assertion might be helpful for now.

Move idr preallocation out of stateid initialization, into stateid
allocation, so that we no longer have to handle any errors from the
former.
This is a little subtle due to the way the idr code manages these
preallocated items--document that in comments.
Signed-off-by: J. Bruce Fields <bfields@redhat.com>
Creating a new file is an irrevocable step--once it's visible in the
filesystem, other processes may have seen it and done something with it,
and unlinking it wouldn't simply undo the effects of the create.
Therefore, in the case where OPEN creates a new file, we shouldn't do
the create until we know that the rest of the OPEN processing will
succeed.
For example, we should preallocate a struct file in case we need it
until waiting to allocate it till process_open2(), which is already too
late.
Signed-off-by: J. Bruce Fields <bfields@redhat.com>
If process_open1() creates a new open owner, but the open later fails,
the current code will leave the open owner around. It won't be on the
close_lru list, and the client isn't expected to send a CLOSE, so it
will hang around as long as the client does.
Similarly, if process_open1() removes an existing open owner from the
close lru, anticipating that an open owner that previously had no
associated stateid's now will, but the open subsequently fails, then
we'll again be left with the same leak.
Fix both problems.

There doesn't seem to be any harm to renewing the client a bit earlier,

renew_client calls over quite so many places.

Use a separate stateid idr per client, and lookup a stateid by first
finding the client, then looking up the stateid relative to that client.
Also some minor refactoring.
This allows us to improve error returns: we can return expired when the
clientid is not found and bad_stateid when the clientid is found but not
the stateid, as opposed to returning expired for both cases.
I hope this will also help to replace the state lock mostly by a
per-client lock, but that hasn't been done yet.

Yet another open-management regression:
- nfs4_file_downgrade() doesn't remove the BOTH access bit on
downgrade, so the server's idea of the stateid's access gets
out of sync with the client's. If we want to keep an O_RDWR
open in this case, we should do that in the file_put_access
logic rather than here.
- We forgot to convert v4 access to an open mode here.
This logic has proven too hard to get right. In the future we may
consider:
- reexamining the lock/openowner relationship (locks probably
don't really need to take their own references here).
- adding open upgrade/downgrade support to the vfs.
- removing the atomic operations. They're redundant as long as
this is all under some other lock.
Also, maybe some kind of additional static checking would help catch
O_/NFS4_SHARE_ACCESS confusion.

Look up closed stateid's in the stateid hash like any other stateid
rather than searching the close lru.
This is simpler, and fixes a bug: currently we handle only the case of a
close that is the last close for a given stateowner, but not the case of
a close for a stateowner that still has active opens on other files.
Thus in a case like:
open(owner, file1)
open(owner, file2)
close(owner, file2)
close(owner, file2)
the final close won't be recognized as a retransmission.

Including the full clientid in the on-the-wire stateid allows more
reliable detection of bad vs. expired stateid's, simplifies code, and
ensures we won't reuse the opaque part of the stateid (as we currently
do when the same openowner closes and reopens the same file).
Signed-off-by: J. Bruce Fields <bfields@redhat.com>
Keep around an unhashed copy of the final stateid after the last close
using an openowner, and when identifying a replay, match against that
stateid instead of just against the open owner id. Free it the next
time the seqid is bumped or the stateowner is destroyed.
