Added LL_IOC_GETPARENT to retrieve the <parent_fid>/name(s) of a given
entry, based on its link EA. This saves multiple calls to
path2fid/fid2path.
Merged with second later patch that does various cleanups.
Avoid unneeded allocation. Get read-only attributes from the user
getparent structure and write the modified attributes only, instead
of populating a whole structure in kernel and copying it back.

Move directory entries cache from llite to MDC, so client
side dir stripe will use independent hash function(in LMV),
which does not need to be tightly coupled with the backend
storage dir-entry hash function. With striped directory, it
will be 2-tier hash, LMV calculate hash value according to the
name and hash-type in layout, then each MDT will store these
entry in disk by its own hash.

Separate master stripe with master object, so
1. stripeEA only exists on master object.
2. sub-stripe object will be inserted into master object
as sub-directory, and it can get the master object by "..".
By this, it will remove those specilities for stripe0 in
LMV and LOD. And also simplify LFSCK, i.e. consistency check
would be easier.
When then master object becomes an orphan, we should
mark all of its sub-stripes as dead object as well,
otherwise client might still be able to create files
under these stripes.
A few fixes for striped directory layout lock:
1. stripe 0 should be locked as EX, same as other stripes.
2. Acquire the layout for directory, when it is being unliked.

1. client send create request to the master MDT, which
will allocate FIDs and create slaves. for all of slaves.
2. Client needs to revalidate slaves during intent getattr
and open request.
3. lmv_stripe_md will include attributes(size, nlink etc)
from all of stripe, which will be protected by UPDATE lock.
client needs to merge these attributes when update inode.
4. send create request to the MDT where the file is located,
which can help creating master stripe of striped directory.

There are several obsolete sub commands for lfs to work with
remote client. We do not support that anymore, and should be
deleted along with any kernel code related to remote client.

Since SUN is no longer around and there's no point in contacting them,
just remove that whole thing. Copy of GPL is available online anyway
(URLs to be updated in next patch).

Pull staging and IIO driver updates from Greg KH:
"Here's the big staging and iio driver update for 4.7-rc1.
I think we almost broke even with this release, only adding a few more
lines than we removed, which isn't bad overall given that there's a
bunch of new iio drivers added.
The Lustre developers seem to have woken up from their sleep and have
been doing a great job in cleaning up the code and pruning unused or
old cruft, the filesystem is almost readable :)
Other than that, just a lot of basic coding style cleanups in the
churn. All have been in linux-next for a while with no reported
issues"

Note that lustre has its private mutex protecting directory pagecache;
if they ever remove it, they'll need to be careful with PageChecked()
use.

The printing of i_ino/i_generation in llite messages is not nearly so
useful as printing the full inode FID, since i_ino is a "compressed"
version of the FID and there may be duplicate values for i_ino in some
cases (especially if running on a 32-bit client).
All instances of printing i_ino/i_generation are replaced with
the FID using ll_inode2fid(). All instances, except for one, of
printing just i_ino was replaced by printing the FID. In all
CERROR lines touched by the i_ino replacements, the device name
or fsname was added at the beginning of the message if it did not
already exist.

Fix 'NULL pointer dereference' defects found by Coverity version
6.5.0:
Dereference after null check (FORWARD_NULL)
For instance, Passing null pointer to a function which dereferences
it.
Dereference before null check (REVERSE_INULL)
Null-checking variable suggests that it may be null, but it has
already been dereferenced on all paths leading to the check.
Dereference null return value (NULL_RETURNS)

If an error occurs when initializing a HSM request, in
ll_ioc_copy_start(), the PROGRESS message, sent to coordinator, should
carry the error code but also HP_FLAG_COMPLETED to mark the request as
finished (with error). If not, the Coordinator will ignore this
message and consider the request is still running.
