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:CC [M] fs/nfsd/nfssvc.o

fs/nfsd/nfssvc.c:335: error: 'THIS_MODULE' undeclared (first use in this function)

fs/nfsd/nfssvc.c:335: error: for each function it appears in.)

These files were getting via an implicit include
path, but we want to crush those out of existence since they cost

If we create the object and then return failure to the client, we're

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
-
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
-
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,
when it is looked up. That saves us from having to sprinkle
renew_client calls over quite so many places.Also remove a redundant comment and do a little cleanup.

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.Signed-off-by: J. Bruce Fields
