Added the code to set mount option for enabling the dirdata in

get_dtype() to decide whether to pass dirdata flag as well while
reading the file type.

Problem has been encountered causing sanity-hsm/test_402 errors

Also, now that copytool will exit earlier, HSMTOOL_NOERROR variable

LU-4529 quota: call qsd_op_end() after trasn stop

qsd_op_end() shouldn't be called before the transaction stopped,
because qsd_op_end() is a quite heavy operation which could
probably allocate memory with standard allocator flag (__GFP_IO),
and allocating memory could result in dirty flush on other
filesystems, that will lead to opening transaction on different
journal and trigger the assert in jbd2_journal_start():
J_ASSERT(handle->h_transaction->t_journal == journal) at the end.

LU-4861 osc: a deadlock problem in osc completion ast

In osc_ldlm_completion_ast(), it tries to hold mutex of cl_lock
and update the lock even it's known that the lock is not granted,
this can introduce a deadlock case if the process is matching a
dlm lock with the calling stack:
  osc_lock_enqueue()
    -> osc_enqueue_base()
      -> ldlm_lock_match()
        -> osc_ldlm_completion_ast()
          -> cl_lock_mutex_get()
The enqueuing lock and the lock for completion_ast() are different
lock. This is a deadlock case because we're holding a lock's mutex
and then request the other.

It's not necessary to acquire the lock in completion_ast() if it's
known that the lock has not been granted.

LU-5053 ptlrpc: Add schedule point to ptlrpc_check_set()

Most ptlrpc sets are believed to be small and bounded in length.  However
at the very least the ptlrpcd reuses the ptlrpc sets at its primary work
queue.  This work queue can easily have work added faster than the ptlrpcd
thread can process the work.  The unbounded work can lead to the ptlrpcd
monopolizing a CPU for hundreds of seconds.  Obviously a well-behaved
kernel function should obey the scheduler and share the processor.

We address that problem by inserting a cond_resched() at the top of the
main loop of ptlrpc_check_set().

Some have suggested putting the cond_resched() lower in the loop.  However,
the only current way to bound the number of loops that we exceed our
allocated run time is to put the call at the top of the loop.  Putting it
lower would allow an unknown number (and since it is unknown, it might be
excessively large at times) of cycles through the loop before a
resched is allowed.
