LU-8025 llite: make vvp_io_write_start lockless for newer kernels

When support for newer kernels was backported from the
upstream kernel it lacked any of the enhancements done
for newer version of lustre. This work makes the newer
kernel support lockless writes like the rest of the
lustre llite code.

LU-8408 mgc: handle config_llog_data::cld_refcount properly

Originally, the logic of handling config_llog_data::cld_refcount
is some confusing, it may cause the cld_refcount to be leaked or
trigger "LASSERT(atomic_read(&cld->cld_refcount) > 0);" when put
the reference. This patch clean related logic as following:

1) When the 'cld' is created, its reference is set as 1.

2) No need additional reference when add the 'cld' into the list
   'config_llog_list'.

3) Inrease 'cld_refcount' when set lock data after mgc_enqueue()
   done successfully by mgc_process_log().

4) When mgc_requeue_thread() traversals the 'config_llog_list',
   it needs to take additional reference on each 'cld' to avoid
   being freed during subsequent processing. The reference also
   prevents the 'cld' to be dropped from the 'config_llog_list',
   then the mgc_requeue_thread() can safely locate next 'cld',
   and then decrease the 'cld_refcount' for previous one.

5) mgc_blocking_ast() will drop the reference of 'cld_refcount'
   that is taken in mgc_process_log().

6) The others need to call config_log_find() to find the 'cld'
   if want to access related config log data. That will increase
   the 'cld_refcount' to avoid being freed during accessing. The
   sponsor needs to call config_log_put() after using the 'cld'.

7) Other confused or redundant logic are dropped.

On the other hand, the patch also enhances the protection for
'config_llog_data' flags, such as 'cld_stopping'/'cld_lostlock'
as following.

a) Use 'config_list_lock' (spinlock) to handle the possible
   parallel accessing of these flags among mgc_requeue_thread()
   and others config llog data visitors, such as mount/umount,
   blocking_ast, and so on.

b) Use 'config_llog_data::cld_lock' (mutex) to pretect other
   parallel accessing of these flags among kinds of blockable
   operations, such as mount, umount, and blocking ast.

The 'config_llog_data::cld_lock' is also used for protecting
the sub-cld members, such as 'cld_sptlrpc'/'cld_params', and
so on.

LU-8454 llite: normal user can't set FS default stripe

Current client doesn't check permission before updating filesystem
default stripe on MGS, which isn't secure and obvious.

Since we setattr on MDS first, and then set default stripe on MGS,
we can just return error upon setattr failure.

Now filesystem default stripe is stored in ROOT in MDT, so saving
it in system config is for compatibility with old servers, this
will be removed in the future.

Add sanity 65m to verify this.

LU-7650 o2iblnd: handle mixed page size configurations.

Currently it is not possible to send LNet traffic between
two nodes using infiniband hardware that have different
page sizes for the case when RDMA fragments are used.
When two nodes establish a connection they tell the other
node the maximum number of RDMA fragments they support.
The issue is that the units are pages, and 256 64K pages
corresponds to 16MB of data, whereas a 4K page system is
limited to messages with 1MB of data. The solution is to
report over the wire the maximum number of fragments in
4K unites regardless of the native page size. The recipient
then uses its native page size to translate into the
maximum number of pages sized fragments it can send to
the other node.

LU-7117 osp: set ptlrpc_request::rq_allow_replay properly

In ptlrpc layer, if the ptlrpc_request::rq_allow_replay is set,
then such RPC can be sent to remote peer even if it is not the
replay RPC during the remote server recovery. Such flag is used
for sending RPC under the case of current server and the remote
server are both in recovery.

On the other hand, abusing such flag will cause some trouble.
For example: consider DNE mode, assume the MDT_m is in recover,
the MDT_n is healthy. At that time, one client can send a normal
reint unlink RPC to the MDT_n to remove the file_A (that resides
on the MDT_n) under the dir_B (that resides on the MDT_m). Under
such case, the MDT_n needs to lookup the dir_B with the file_A's
name, means the MDT_n needs to send lookup OUT RPC to the MDT_m,
but before that it needs to lock the dir_B with LDLM_ENQUEUE RPC
firstly. Because the MDT_m is recovering, since the LDLM_ENQUEUE
RPC is not for replay, it should be blocked until the recovery
done on the MDT_m. That is expected behavior. But if the MDT_n
(via OSP) sets ptlrpc_request::rq_allow_replay improperly, then
such LDLM_ENQUEUE RPC may be sent to the MDT_m during the MDT_m
recovery and granted without conflict. And then the subsequent
lookup OUT RPC may obtain some stale information from the MDT_m
if the dir_B has NOT been recovered yet.

So the ptlrpc_request::rq_allow_replay will be set during current
MDT recovery. On the other hand, there are multiple threads those
are related with the recovery, such as target_recovery_thread and
lod_sub_recovery_thread. Because the obd_device::obd_recovering
is controlled by the target_recovery_thread that is started later
than the lod_sub_recovery_thread. Only checking the obd_recovering
flag does not work under some cases. So it needs to check other
flags: obd_device::obd_replayable and obd_device::obd_no_conn to
distinguish recovery related RPC properly.

So for above case, the client sponsored unlink will be blocked on
the MDT_n for the LDLM_ENQUEUE RPC until the MDT_m recovery done.
