LU-5508 osp: RPC adjustment for remote transaction
1) For remote transaction, the set_attr/set_xattr RPC should not be
prepared in declare phase. According to our current transaction/
dt_object_lock framework, the transaction sponsor will start the
transaction firstly, then try to acquire related dt_object_lock
if needed. That is a general rule, and the LFSCK needs to follow
such rule when repair inconsistent linkEA, in spite of local or
remote MDT-object.
For linkEA repairing case, before the LFSCK thread obtained the
dt_object_lock on the target MDT-object, it cannot know whether
the MDT-object has linkEA or not, neither invalid or not.
Since the LFSCK cannot hold dt_object_lock before the (remote)
transaction start (otherwise there will be potential deadlock),
it cannot prepare related RPC for repairing during the declare
phase as other normal transactions do.
To resolve the trouble, we will make OSP to prepare related RPC
(set_attr/set_xattr/del_xattr) after remote transaction started,
and trigger the remote updating (RPC sending) when trans_stop.
Then the up layer users, such as LFSCK, can follow the general
rule to handle trans_start/dt_object_lock for repairing linkEA
inconsistency without distinguishing remote MDT-object.
2) Some adjustment for OSP object attributes cache maintainig to make
the logic more clear and reasonable.
2.1) Update the cached attribute in osp_attr_set(), but not in the
osp_declare_attr_set().
2.2) Update the cached extended attribute in osp_xattr_set(), but not
in the osp_declare_xattr_set().
2.3) Drop the cached extended attribute in osp_xattr_del().
3) Typo fixing and code cleanup.

LU-1669 vvp: Use lockless __generic_file_aio_write
Testing multi-threaded single shard file write performance has shown
the inode mutex to be a limiting factor when using the
generic_file_aio_write function. To work around this bottle neck, this
change replaces the locked version of that call with the lock less
version, specifically, __generic_file_aio_write.
In order to maintain posix consistency, Lustre must now employ it's
own locking mechanism in the higher layers. Currently writes are
protected using the lli_write_mutex in the ll_inode_info structure.
To protect against simultaneous write and truncate operations, since
we no longer take the inode mutex during writes, we must down the
lli_trunc_sem semaphore.
Unfortunately, this change by itself does not garner any performance
benefits. Using FIO on a single machine with 32 GB of RAM, write
performance tests were ran with and without this change applied; the
results are below:

In order to garner any real performance benefits out of a single

follow up patch.

Testing has shown the ll_inode_inode's lli_write_mutex to be a
limiting factor with single shared file write performance, when using
many writing threads on a single machine. Even if each thread is
writing to a unique portion of the file, the lli_write_mutex will
prevent no more than a single thread to ever write to the file

This change attempts to remove this bottle neck, by replacing this

to a single file simultaneously iff the threads are writing to unique

* newly allocated sai will hold one refcount, and it will put it

* statahead thread holds one refcount.

sles11sp3 is the only currently supported distro where that is true.
New code in osd-ldiskfs that is conditional when
HAVE_LDISKFS_MAP_BLOCKS is set by autoconf calls ldiskfs_map_blocks.
That entry point exists in ext4/ldiskfs code, but isn't exported with

osd-ldiskfs with an error like:

LU-5395 lfsck: deadlock between LFSCK and destroy
There is potential deadlock race condition between object
destroy and layout LFSCK. Consider the following scenario:
1) The LFSCK thread obtained the parent object firstly, at
that time, the parent object has not been destroyed yet.
2) One RPC service thread destroyed the parent and all its
children objects. Because the LFSCK is referencing the
parent object, then the parent object will be marked as
dying in RAM. On the other hand, the parent object is
referencing all its children objects, then all children
objects will be marked as dying in RAM also.
3) The LFSCK thread tries to find some child object with
the parent object referenced. Then it will find that the
child object is dying. According to the object visibility
rules: the object with dying flag cannot be returned to
others. So the LFSCK thread has to wait until the dying
object has been purged from RAM, then it can allocate a
new object (with the same FID) in RAM. Unfortunately, the
LFSCK thread itself is referencing the parent object, and
cause the parent object cannot be purged, then cause the
child object cannot be purged also. So the LFSCK thread
will fall into deadlock.
We introduce non-blocked version lu_object_find() to allow
the LFSCK thread to return failure immediately (instead of
wait) when it finds dying (child) object, then the LFSCK
thread can check whether the parent object is dying or not.
So avoid above deadlock.

LU-5443 lnet: replace direct HZ access with kernel APIs
On some customers’ systems, kernel was compiled with HZ defined to
100, instead of 1000. This improves performance for HPC applications.
However, to use these systems with Lustre, customers have to re-build
Lustre for the kernel because Lustre directly uses the defined
constant HZ.
Since kernel 2.6.21, some non-HZ dependent timing APIs become non-
inline functions, which can be used in Lustre codes to replace the
direct HZ access.
These kernel APIs include:
jiffies_to_msecs()
jiffies_to_usecs()
jiffies_to_timespec()
msecs_to_jiffies()
usecs_to_jiffies()
timespec_to_jiffies()
And here are some samples of the replacement:
HZ -> msecs_to_jiffies(MSEC_PER_SEC)
n * HZ -> msecs_to_jiffies(n * MSEC_PER_SEC)
HZ / n -> msecs_to_jiffies(MSEC_PER_SEC / n)
n / HZ -> jiffies_to_msecs(n) / MSEC_PER_SEC
n / HZ * 1000 -> jiffies_to_msecs(n)
This patch replaces the direct HZ access in lnet module.

LU-5406: liblustre: remove \n from some llapi_error strings
Some strings passed to llapi_error() contain a \n. But llapi_error's
callback, error_callback_default(), adds one too. So fix these strings.
Converted a few spaces to tabs.
