staging/lustre/osc: Update inode timestamp for lockless IO as well

Removed the checks for oi_lockless from osc_io_read_start() and
osc_io_write_start(). This patch also removes the unnecessary call to
cl_object_attr_get() in osc_io_write_start() before calling

staging/lustre/clio: replace semaphore with mutex

According https://www.kernel.org/doc/Documentation/mutex-design.txt:
- the mutex subsystem is slightly faster and has better scalability
  for contended workloads. In terms of 'ops per CPU cycle', the
  semaphore kernel performed 551 ops/sec per 1% of CPU time used,
  while the mutex kernel performed 3825 ops/sec per 1% of CPU time
  used - it was 6.9 times more efficient.
- there are no fastpath tradeoffs, the mutex fastpath is just as
  tight as the semaphore fastpath. On x86, the locking fastpath is
  2 instructions.
- 'struct mutex' semantics are well-defined and are enforced if
  CONFIG_DEBUG_MUTEXES is turned on. Semaphores on the other hand
  have virtually no debugging code or instrumentation.

One more benefit of mutex is optimistic spinning. It try to spin for
acquisition when there are no pending waiters and the lock owner is
currently running on a (different) CPU. The rationale is that if the
lock owner is running, it is likely to release the lock soon.

This significantly reduce amount of context switches when locked
region is small and we have high contention.

stagaing/lustre: Improve statahead debug messages

The statahead debug messages include the pid of the current
process in their body.  This is both redudant (because all
lustre log messages contain the pid), and sometimes downright
misleading.  For instance the messages would say something like
"stopping statahead thread 3446".  One would probably think
that 3446 is the pid of the process that is being stopped,
but in fact it was the pid of the caller issuing the stop signal.

We remove all superfluous pids from the messages.

Next we have the ll_statahead_thread() and the ll_agl_thread() record
their respective pids in their respective ptlrpc_thread structures.
This allows to print the pid of the thread that we are trying to
stop (which is actually useful info) from other threads, such as those
calling ll_stop_statahead().

staging/lustre/llite: Avoid statahead thread start/stop deadlocks

The statahead and statahead agl threads blindly set their
thread state to SVC_RUNNING without checking the state first.  If, for
instance, another thread sets the state to SVC_STOPPING that
stop signal will now have been lost.  Deadlock ensues.

We also partly improve the sai reference counting, because a race exists
where the ll_stop_statahead thread can drop the default reference, and
the statahead thread can exit and drop its reference as well.  With no
references on the sai, the final put will poison and free the buffer.  The
original do_statahead_enter() function may then continue to access
the buffer after it is freed because it did not take a reference of its

staging/lustre: Limit reply buffer size

When allocating a reply buffer for the striping information don't
assume the unlikely worst case.  Instead, assume the common case
and size the buffer based on the observed default ea/cookie size.

The default size is initialized to a single stripe and allowed to
grow up to an entire page if needed.  This means that for smallish
filesystems (less than ~21 OSTs) where the worst case striping
information can fit in a single page there is effectively no
change.  Only for larger filesystem will the default be less than
the maximum.  This has a number of advantages.

* By limiting the default reply buffer size we avoid always
  vmalloc()'ing the buffer because it exceeds four pages in size
  and instead kmalloc() it.  This prevents the client from
  thrashing on the global vmalloc() spin lock.

* A reply buffer of exactly the right size (no larger) is allocated
  in the overflow case.  These larger reply buffers are still
  unlikely to exceed the 16k limit where a vmalloc() will occur.

* Saves memory in the common case.  Wide striped files exceeded
  the default are expected to be the exception.

The reason this patch works is because the ptlrpc layer is smart
enough to reallocate the reply buffer when an overflow occurs.
Therefore the client doesn't have to drop the incoming reply and
send a new request with a larger reply buffer.

It's also worth mentioning that the reply buffer always contains
a significant amount of extra padding because they are rounded up
to the nearest power of two.  This means that even files striped
wider than the default have a good chance of fitting in the
allocated reply buffer.

Also remove client eadatasize check in mdt xattr packing because
as said above client can handle -EOVERFLOW.

staging/lustre: restore __GFP_WAIT flag to memalloc calls

In Lustre 2.4, the flags passed to the memory allocation functions are
translated from CFS enumeration values types to the kernel GFP
values by calling cfs_alloc_flags_to_gfp(). This function adds
__GFP_WAIT to all flags except CFS_ALLOC_ATOMIC. In 2.5, when
the cfs wrappers were dropped, cfs_alloc_flags_to_gfp() was
removed and the CFS_ALLOC_xxxx was simply replaced with __GFP_xxxx.
This means that most memory allocation calls are missing the
__GFP_WAIT flag. The result is that Lustre experiences more ENOMEM
errors, many of which the higher levels of Lustre do not handle
robustly.
Notes GFP_NOFS = __GFP_WAIT | __GFP_IO. So the patch replaces
__GFP_IO with GFP_NOFS.
Patch does not add __GFP_WAIT to GFP_IOFS. GFP_IOFS was not used in
Lustre 2.4 so it has never been used with __GFP_WAIT.

Rewrite the old thread based code to use a workqueue instead. This
removes a pile of complexity, locks and queues and eliminates problem
that cmd handling could have been killed from userspace.
