LU-1603 ofd: Fix null pointer dereferences in ldiskfs_statfs()

On an OSS running the OFD-OSD stack, unmounting all OSTs makes all OFD
and OSD keys (i.e., lu_context_key) quiescent.  Next time the OSTs are
remounted, ofd_stack_init() will try to refill the quiescent osd_key
into the context, resulting in a null pointer dereference in
ldiskfs_statfs().  Before the problem motivating LCT_QUIESCENT and
LCT_REMEMBER can be revisited, the solution is to refill contexts
after new device types have been "revived" via allocations of their
first device instances.

lnet_nid2peer_locked()->lnet_find_peer_locked() will get NULL if
LNet's in progress of shutting down, then it will try to allocate
a new peer and insert it into peer table. If one thread is doing this
and another thread could have already finalized everything of LNet,
so the first thread will crash system after allocation.

The solution is add an extra refcount on peer-table (number of peers)
before allocating new peer, because the shutting down thread always
needs to wait until peers number to be zero before going to the

LU-521 lnet: make LST support variable page size

LNet selftest can't support variable page size because it sends
number of pages over the wire.
We have to change wire format to fix this but it will have
compatibility issue, so this patch also implemented "session features"
for LST to resolve compatibility issue, only new version LST
can understand new bulk RPC format, although new LST nodes still can
communicate with old LST nodes.

The Variable page size feature can be turned on by setting
LST_FEATURES to LST_FEAT_BULK_LEN (1). This feature is off by default.

Please see the Jira ticket (LU-521) for more details.

LU-1239 ldlm: cascading client reconnects

It may happen that
- MDS is overloaded with enqueues, they consume all the threads on
  MDS_REQUEST portal and waiting for a lock a client holds;
- that client tries to re-connect but MDS is out of threads and
  re-connection fails;
- other clients are waiting for their enqueue completions, they try
  to ping MDS if it is still alive, but despite the fact it is a HP-rpc,
  there is no thread reserved for it. Thus, other clients get timed
  out as well.

Ensure each service which handles HP-rpc has an extra thread reserved
for them; make MDS_CONNECT and OST_CONNECT HP-rpc.

LU-56 ptlrpc: partitioned ptlrpc service

Current ptlrpc service only have a per-service instance, all service
threads share locks and request queue of this instance, this causes
many perforamnce issues like heavy lock contention and data/threads
migration between CPUs/NUMA nodes.

This patch created per-partition data for ptlrpc service, each service
have locks/request-queues on each partition, also, service will have
CPT (CPU partition) affinity threads on each partition, threads
bond on a CPT will only access data on local partition, this feature
should decrease lock contention and data/thread migration and improve
server side performance.

Another change is we use cfs_hash to replace big array fo_iobuf_pool
in obdfilter, filter_iobuf can be found by from the hash by thread ID.
The reason we made this change is because we removed absolute limit
of ptlrpc threads number, which means we have no idea how big the
fo_iobuf_pool should be. Also, even we have obsolute limit of threads
number, it's still dangerous to use a pre-allocated array because
it's difficult to guarantee thread ID to be contiguous if we want
to shrink threads in the future.

LU-957 lfsck: LFSCK main engine

Implement the main engine for Lustre online fsck. The kernel
thread "lfsck" scans the system object table by low layer DT

It is the controller for the whole LFSCK, and controls the

we need to rebuild the OI files ASAP, then low layer OI scrub

LU-1415 tests: Basic support for ZFS-based servers

This patch extends Test Framework to support formatting and mounting
ZFS-based servers.

Current global FSTYPE is no longer flexible enough, as different
facets can use different types of back ends.  Such "mixed-fstype"
configurations are firstly resulted from the incremental landing of
Orion changes.  For example, when we have OFD and ZFS OSD, although
OSTs will be able to use ZFS, MGS and MDTs can still only use LDiskFS.
Secondly, to reduce the test matrix, we may also want to have both
OSTs using LDiskFS and OSTs using ZFS in the same test cluster.
Hence, this patch makes back end file system type a per-facet
attribute.  The flexible configuration variables in local.sh are
reserved for users; all other scripts shall use facet_fstype()
instead.

The major differences between using an LDiskFS-based target and a
ZFS-based one are on the mkfs.lustre(8) command line:

  - ZFS-based targets shall have "--backfstype=zfs", while
    LDiskFS-based ones shall have "--backfstype=ldiskfs".

  - LDiskFS-specific "--mkfsoptions" arguments shall not be given to
    ZFS-based targets, and vice versa.

  - ZFS-based targets have different device specifications.  See
    mkfs.lustre(8).

In addition, we will make "--index" mandatory.  Naturally, format
options have to be generated for each facet dynamically, based on its
back end type, index, etc.  This patch changes mkfs_opts() to do
exactly that.  All test scripts shall use mkfs_opts() instead of
reading related environment variables directly.

Similarly, mount options should also be generated on a per-facet, or
at least per-fstype, basis.  Nevertheless, this patch takes a shortcut
by keeping current per-facet-type {MGS,MDS,OST}_MOUNT_OPTSs and
generating the "loop" mount option dynamically in mount_facet().  I
believe this solution introduces fewer changes comparing to a pure
per-facet one and is sufficient for current use cases.

This patch is based on Brian Behlendorf's work under ORI-155.  See
http://review.whamcloud.com/1417.

LU-56 obdclass: SMP improvement for lu_key

ptlrpc service threads need to call lu_context_init/fini in each
loop (for each RPC), this could be a big performance issue on
fat SMP machine if we always add lu_context to remember list
because operations on lu_context with LCT_REMEMBER are serialized
by one spinlock and we need to lock/unlock it for multiple times
for each RPC.

But we found LCT_REMEMBER is abused at here, it's impossible that
server stack is being unloaded but service threads are still
running, so we can simply remove LCT_REMEMBER flag from ->rq_session,
and made some small changes to bypass global lock in lu_context_init
and lu_context_fini if w/o LCT_REMEMBER.
