LU-6245 libcfs: make libcfs_ioctl.h and lnetctl.h uapi compliant

For UAPI headers the policy is to only have data
structures shared between user land and kernel
space. All non data structures except a reference
to libcfs_ioctl_data_adjust() have been removed.
libcfs_ioctl_data_adjust can go away when the two
module.c files for libcfs will merger. For lnetctl.h
we remove userland only function prototypes.h

LU-6684 lfsck: set the lfsck notify as interruptable

If the LFSCK engine is notifying the remote LFSCK engine about some
LFSCK event, such as LE_PHASE1_DONE, but if the remote server (MDT
or OST) is offline, then such notification RPC will be blocked until
the remote server is online. At that time, if someone wants to stop
the LFSCK, he/she has to wait.

To avoid such trouble, we will make the LFSCK notification RPC to
be interruptable. Then even if some remote server is offline, the
running LFSCK still can be stopped.

LU-3538 dne: Commit-on-Sharing for DNE

This patch contains three parts:
1. Sync-on-Cancel for cross-MDT lock, which eleminates dependency
   between transactions and distributed transaction which modified
   remote object, this can guarantee the change of the distributed
   transaction will not be lost.
2. enable Commit-on-Sharing for DNE, PW/EX locks will be converted
   to COS locks, but by default they are ignored, when operation
   finds itself a distributed transaction, it will lock with
   LDLM_FL_COS_INCOMPAT flag to check against existed COS locks.
   This will eliminate dependency between distributed transaction
   and transactions which modify the same local object, and it
   guarantees distributed transaction can always be recovered.
3. striped directory creation needs to ensure its parent permanent
   on disk, to ensure this, cache child locks in mkdir.

Sync-on-Cancel for cross-MDT lock

When two operations have dependency on an object, and the first
operation has a PW/EX cross-MDT lock on this object, trigger
transaction commit on the MDT where the object resides to
eliminate dependency, in short, this patch eliminates dependency
between locks and existed PW/EX cross-MDT lock.

This patch contains following changes:
* enable Sync on Cancel for DNE by default.
* save cross-MDT lock into tgt_uncommitted_soc_locks after use,
  and it will be released upon transaction commit, note, just
  a lock refcount is taken when lock is saved, the read/write
  count is released in mdt_object_unlock().
* the saved cross-MDT lock will be discarded upon BAST,
  because the MDT where the object resides will do sync on lock
  cancel.
* use existed BLOCKING_SYNC_ON_CANCEL mechanism to commit
  transaction upon cross-MDT lock cancel.

Commit-on-Sharing for DNE

On DNE, Commit-on-Sharing is disabled by default, but MDT local
PW/EX lock will be saved as COS lock, and such lock will be
ignored in compatilibity check by default, unless it's required,
there are two situations:
1. when distributed transaction locks local object, it will
   conflict with COS locks.
2. when distributed transaction enqueues cross-MDT lock, it will
   conflict with COS locks.

This patch contains following changes:
* on DNE, local PW/EX lock is converted to COS and saved like
  before even when COS is not enabled.
* above COS locks will be ignored in lock compatibility check by
  default, so for local operations COS won't take effect. But if
  operation finds itself may modify remote MDT object, it will lock
  all local locks with COS checked.
* cross-MDT lock will always conflict with COS locks.
* if operation is reint, it will check whether it's a distributed
  operation (involved objects are remote or striped) if so, check
  against COS locks when enqueing locks.

Eliminate dependency in dir creation

Mkdir needs to take a lock on child, so that any subsequent
distributed operation using that directory would observe a conflict
and ensure that the original mkdir is committed.

Benchmark result with createmany/unlinkmany is as follows:
        mkdir rmdir open unlink mknod unlink (ops/sec)
2.6     1194 1310 1314 1185 2242 1396
master   978 1166  937 1028 1681 1202
current  930 1161  918 1018 1691 1202

* 10 createmany/unlinkmany processes running on local client
  (on MDS), 4M dirs/files created/unlinked, and the numbers are
  average of 10 processes.
* for 2.6, each process is running on a separate mountpoint.

LU-7039 llog: update llog header and size

Once update request fails due to eviction or other failures,
all of update request in the sending list should return fail,
because after the failure, the update log in the following
request will have wrong llog bitmap. So once this happens,it
will

1. invalidate all of requests in the sending list.
2. lod_sub will update the llog header from remote target.
3. Then Sending list can accept new request.

Also a few other fixes for llog corruption

1. Because the size in OSP cache is not safe, because no lock
protect it. So we will add lgh_write_offset in loghandle to
track the write offset for remote update llog, and revalidate
the offset during updating the llog header.

2. rollback the lgh_index and bitmap once add new records
fails.

Add replay-single.sh 118 to verify the case.

LU-6939 nrs: add lock to protect TBF rule linkage

Due to lack of lock protection for operations on rule's list of
client (nrs_tbf_rule->tr_cli_list), it leads to assertion panic

Also, some of the fields of rule is inited earlier in

A race condition has been found where connd is cleaning up failed
connections, the peer ref counter goes to zero, but we stil have
a connecting counter > 0.

One possible race is when we are retrying a connection by
calling kiblnd_connect_peer() which itself fails and decrements
the peer ref counter and gets swapped out before it can decrement

counter of 1.  This will trigger the assert seen in LU-7210 when
it decrements the peer counter.

The solution: be sure to decrement the connecting counter
before decrementing the peer counter in the peer connect
failure path.

1GB, and in fact users are likely to hit ENOSPC when reaching half of
limit because of bad hash. tested by following scripts.

i=0
filename="aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbbbbb"

do
        touch $filename"$i"
        if [ $? -ne 0 ];then
                break
        fi
        ((i++))
done

When directoy size grow about 590M, we hit ENOSPC. Better way is to
add support to e2fsprogs so that we can use large dir feature.
As a walkaround way, this patch try to give warning messages to
console when 10/16 and 11/16 of limit reach.

So this patch will try to give following messages when warning

Directory (inode: 8388610 FID: [0x200000401:0x1:0x0]) has approached

Directory (inode: 8388610 FID: [0x200000401:0x1:0x0]) is approaching
