LU-8391 ldlm: check double grant race after resource change

In ldlm_handle_cp_callback(), we call lock_res_and_lock and then
check if the ldlm lock has already been granted.
If the lock resource has changed, we release the lock and go ahead
allocating new resource, then grabs the lock again before calling
ldlm_grant_lock().
However this gives another thread an opportunity to grab the lock
and pass the check, while we change the resource. Eventually the
other thread calls ldlm_grant_lock() on the same ldlm lock and
triggers a LASSERT.

Fix the issue by doing double grant race check after changing the
lock resource.

LU-11199 mdt: Attempt lookup lock on open

Commit 4f50273a (LU-10269 ldlm: fix the issues introduced
by try bits) changed the locking behavior on open to not
attempt to grant the LOOKUP lock bit.  This causes a
performance regression in open(), which is up to 75% in
some benchmarks, such as mdsrate (from lustre/tests/mpi):

First create the files:
mpirun -n 4 /usr/lib64/lustre/tests/mdsrate /
-d /mnt/lustre/mdsrate --create --nfile=30000

Then drop caches:
echo 3 > /proc/sys/vm/drop_caches

Then run the open benchmark:
mpirun -n 4 /usr/lib64/lustre/tests/mdsrate /
-d /mnt/lustre/mdsrate --open --iters 8000 --nfile=30000
[More details in LU-1199]

This patch reverts that specific part of 4f50273a, which
restores open() performance to prior levels.

It may not be 100% correct to ask for open only when
also asking for layout, but this is the earlier behavior.

There is a further patch in flight to optimize this
code:
https://review.whamcloud.com/32156

And further changes are left for that patch.

LU-11454 ptlrpc: Make CPU binding switchable

LU-6325 added CPT binding to the ptlrpc worker threads on
the servers.  This is often desirable, especially where
NUMA latencies are high, but it is not always beneficial.

If NUMA latencies are low, there is little benefit, and
sometimes it can be quite costly:

In particular, if NID-CPT hashing with routers leads to an
unbalanced workload by CPT, it is easy to end up in a
situation where the CPUs in one CPT are maxed out but
others are idle.

To this end, we add module parameters to allow disabling
the strict binding behavior, allowing threads to use all
CPUs.

This is complicated a bit because we still want separate
service partitions - The existing "no affinity" behavior
places all service threads in a single service partition,
which gives only one queue for service wakeups.

So we separate binding behavior from CPT association,
allowing us to keep multiple service partitions where
desired.

Module parameters are added to ldlm, mdt, and ost, of the
form "servicename_cpu_bind", such as "mds_rdpg_cpu_bind".

Setting them to "0" will disable the strict CPU binding
behavior for the threads in that service.

Parameters were not added for certain minor services which
do not have any CPT affinity/binding behavior today.  (This
appears to be because they are not expected to be
performance sensitive.)

LU-8950 tests: do not use make_custom_file_for_progress()

Do not use make_custom_file_for_progress() in sanity-hsm in tests:
12c, 26, 27b, 28, 31b, 31c, 33, 34, 35, 36, 54, 55, 56, 60, 62, 71,
104, 200, 202, 221, 223b, 225, 251, 252, 407

Before this patch make_custom_file_for_progress() was used to create
big files (5MB to 40 MB). There were several use cases for that:
 - in combination with the --bandwidth option of lhsmtool_posix, it
   allows synchronizing HSM operations and other things;
 - to log enough "progress events", HSM operations need to last long
   enough (the --bandwidth option comes in handy too).

It needed to be removed because:
 - archiving and restoring big files at a 1MB/s rate takes too much
   time (admittedly, that was the point);
 - there are other way to have HSM operations occur concurently. For
   example: suspending copytools to delay request processing.
 - make_custom_file_for_progress() does not correctly reflect what
   the function does and should be used for. Wherever big file are
   still needed, the patch uses create_file() instead.

Removing the need to archive or restore big files at a limited rate
represents quite a speed-up on sanity-hsm.

LU-8066 llite: change how "dump_page_cache" walks a hash table

The "dump_page_cache" seq_file currently tries to encode
a location in the hash table into a 64bit file index so that
the seq_file can seek to any location.

This is not necessary with the current implementation of seq_file.
seq_file performs any seeks needed itself by rewinding and calling
->next and ->show until the required index is reached.

The required behaviour of ->next is that it always returns the next
object after the last one returned by either ->start or ->next.
It can ignore the ppos, but should increment it.

The required behaviour of ->start is one of:
1/ if *ppos is 0, then return the first object
2/ if *ppos is the same value that was passed to the most recent call
   to either ->start or ->next, then return the same object again
3/ if *ppos is anything else, return the next object after the most
   recently returned one.

To implement this we store a vvp_pgcache_id (index into hash table)
in the seq_private data structure, and also store 'prev_pos' as the
last value passed to either ->start or ->next.

We remove all converstion of an id to a pos, and any limits on the
size of the vpi_depth.

vvp_pgcache_obj_get() is changed to ignore dying objects so that
vvp_pgcache_obj only returns NULL when it reaches the end of a hash
chain, and so vpi_bucket needs to be incremented.

A reference to the current ->clob pointer is now kept as long as we
are iterating over the pages in a given object, so we don't have to
try to find it again (and possibly fail) for each page.

And the ->start and ->next functions are changed as described above.

LU-10030 clio: don't use spare bits in iattr.ia_valid

Using spare bits in iattr.ia_valid is not safe as the
bits might get used for some other purpose without
us noticing.

Lustre currently used 4 spare bit, but they are all
defined in different places so this isn't immediately
obvious.

This patch brings all those bit definitions together
and defined a new op_data field (op_xvalid) to hold
the extra validity bits.

It also replaces sa_valid in struct cl_setattr_io
with sa_avalid and sa_xvalid.  Changing the name is
helpful as sa_valid already has another use within
lustre.

LU-11373 libcfs: fix wrong check in libcfs_debug_vmsg2()

Logic here is we skip output if time is before @cdls_next
reach and increase @cdls_count. however we did it in the
opposite way:

1)libcfs_debug_vmsg2() is called for a long time, that means
current check succeed, we skip print messages and return, we
will skip all messages later too..

2)libcfs_debug_vmsg2() is called frequently, current check
fail every time, message will be bumped out always. the
worst case is we never skip any messages.

Also fix test case to cover this later which is from Andreas:

The test_60a() llog test is being run on the MGS, while the
check in test_60b() to confirm that CDEBUG_LIMIT() works properly
is being run on the client.  There has been a breakage in
CDEBUG_LIMIT() that this test failed to catch, now we need to
track it down.

LU-8066 llite: remove redundant lookup in dump_pgcache

Both the 'next' and the 'show' functions for the dump_page_cache
seqfile perform a lookup based on the current file index.  This is
needless duplication.

The reason appears to be that the state that needs to be communicated
from "next" to "show" is two pointers, but seq_file only provides for
a single pointer to be returned from next and passed to show.

So make use of the new 'seq_private' structure to store the extra
pointer.
So when 'next' (or 'start') find something, it returns the page and
stores the clob in the private area.
'show' accepts the page as an argument, and finds the clob where it
was stored.

LU-6864 mdc: move RPC semaphore code to lustre/osp

The "MDC RPC semaphore" is no longer used by MDC code since patch
http://review.whamcloud.com/14374 "LU-5319 mdc: manage number of

well, it makes sense to move all of this code from MDC to OSP so
that it will also be cleaned up when that functionality lands.

LU-8130 ptlrpc: convert conn_hash to rhashtable

Linux has a resizeable hashtable implementation in lib,
so we should use that instead of having one in libcfs.

This patch converts the ptlrpc conn_hash to use rhashtable.
In the process we gain lockless lookup.

As connections are never deleted until the hash table is destroyed,
there is no need to count the reference in the hash table.  There
is also no need to enable automatic_shrinking.
