LU-8998 lod: accomodate to composite layout

Modify the LOD to make it support the composite layout:

- Introduced lod_layout_component structure to represent each
  individual layout component, and added ldo_comp_entries and
  ldo_comp_cnt in the lod_object structure to hold the striping
  information for composite layout.

- Object allocation code is adjusted to not only check the used
  OSTs in this round of allocation, but also the used OSTs in
  the existing layout components.

- Support special xattr names to add/set/delete layout component(s).

- Store default layout xattr on the filesystem root inode.

- The behavior of option "--param" is improved a little. It will erase

new values specified in the command line.

- For zfs only, the patch introduces a "null value" rule in the form
of "<key>=" to mark a property to be removed from dataset by
zfs_write_ldd() finally.

- To keep the right semantics, if "--erase-params" is specified, all
old parameters should be erased before any new changes are done.

- test_89 conf-sanity.sh is added to verify these new features.

LU-9026 o2iblnd: Adapt to the removal of ib_get_dma_mr()

In Linux kernel 4.9-rc1, the function ib_get_dma_mr()
was removed and a second parameter was added to ib_alloc_pd().

This patch fixes this breakage by:

- Detect if ib_get_dma_mr() has been removed, if so, do the
  following:
- Make it so the module parameter map_on_demand can no longer be
  zero (we have to configure FMR/FastReg pools; it can no longer be
  off).
- No longer try to use the global DMA memory region, but make use
  of the FMR/FastReg pool for all RDMA Tx operations.
- Everywhere we are using the device DMA mr to derive the
  L-key for non-registered memory regions, use the
  pd->local_dma_lkey value instead.
- Make the default map_on_demand = 256.  This will allow nodes with
  this patch to still connected to older nodes without this patch
  and FMR/FastReg turned off.  When FMR/FastReg is turned off, we
  use 256 as the max frags so the two sides will still be able to
  communicate and work.

it's not only badly racy, it's actually dead code - the call in
ll_invalidate_aliases() is unreachable.  For an alias of our inode
to be root dentry, the inode would have to be its ->d_inode, aka
the root inode, and we never call ll_invalidate_aliases() for that.

LU-9153 utils: improve llog name parsing

Current llog name specification is totally non-standard for
lctl llog_print, llog_info, and related commands.  Change this
to accept llog names without the leading '$', since adding '$'
is non-intuitive and the shell will think this is a variable
and "$fsname-client" becomes "-client" unless it is escaped.

Similarly, llog identifiers were formatted like "#0x4:10#0000000"
instead of the standard FID format [0x4:0x10:0x0].  Update the
code to accept and print FIDs in normal format.

Add lctl-llog_print.8, lctl-llog_info.8, lctl-llog_catlist.8 man
pages.

Add a test case for parsing "lctl llog_print" with both old
and new input formats.

LU-5964 tests: open a large number of files at once

the total number of files that can be open at one time.  Also add a
sanity.sh test for this functionality.

Fix handling of last "-seconds" argument, but deprecate positional

more flexible and sustainable in the long term.

Order the include files alphabetically to simplify coding.
Order the argument parsing to be alphabetical to simplify coding.

Use booleans for do_* flags, and don't treat multiple of the same
argument as an error, that doesn't really improve usability at all.

Rename the "-r" option to "-u", to better match "unlinkmany", but
allow both to be accepted for the time being.  Allow "-u" (or "-r")
to be used in isolation to only delete files created in a prior run.
Print stats properly if only "-u" is specified, instead of assuming
that files are always being created in the same pass as deletion.

Print only the short program name instead of all of argv[0].  This
will also simplify multiplexing "createmany" as "unlinkmany" by name
at a later time.

LU-8900 snapshot: check write barrier before modification

For client sponsored modifications, the RPC service thread on the
MDT will check whether there is write barrier or not when creates
transaction handler, if yes, return -EINPROGRESS to the caller.

Generally, the check is done inside mdd_trans_create(). For those
cases that bypass mdd_trans_create(), such as some mdd_iocontrol,
quota, will be checked individually.

For open-unlink case, when close the last open handler, it will
try to destroy the orphan. But if the close-destroy is blocked
by the barrier, the orphan MDT-object will be kept in the MDT's
orphan list and will be destroyed automatically when remount the
MDT next time. Since barrier-snapshot is relative rare operation,
and race with close-destroy will be more rare, such solution is
reasonable and will not cause serious trouble.

When client get the -EINPROGRESS error, the expected behaviour is
to re-try the RPC some time later. That is the standard action on
the client-side, not only for blocked by barrier but also for some
cases, such as the case of related OI mapping is invaid and the OI
scrub is rebuilding the OI files. So there is no interoperability
trouble caused by MDT-side write barrier.

LU-9176 osd-zfs: improve statfs estimate for ZFS

When a ZFS filesystem is newly formatted, there are 128 OI ZAPs and
96 object directories, but only a handful of regular files.  This
skews the average MDT file size to be much larger than regular files,
which in turn makes the estimated total number of files on the MDT
much too small.

Improve the inode size estimate when the filesystem has few files to
be closer to the expected long term average so that the reported total
inode count is reasonable for a new or otherwise empty filesystem.

LU-8900 snapshot: operate write barrier on MDT

Currently, the Lustre barrier is implemented as write barrier
on all MDTs. For each MDT in the system, when it starts, it
registers a barrier instance that will be used in handling
subsequent barrier requests.

The barrier_handler() processes the barrier request: freeze
or thaw the barrier on the MDT. Freezing barrier is the key
part. We use two-phases barrier to guarantee that after the
barrier setup:

1) All the MDT side pending async modifications have been flushed.
2) Any subsequent modification will be blocked.
3) All async transactions on the MDTs have been committed.

For phase1, we do the following:

Firstly, it sets barrier flag on the instance that will block
subsequent modifications from clients. (Note: server sponsored
modification will be allowed for flush pending modifications)

Secondly, it will flush all pending modification via dt_sync(),
such as async OST-object destroy, async OST-object owner changes,
and so on.

If there are some on-handling clients sponsored modifications
during the barrier freezing, then related modifications may cause
pending requests after the first dt_sync(), so call dt_sync()
again after all on-handling modifications done.

With the phase1 barrier set, all pending cross-servers modification
have been flushed to remote servers, and any new modification will
be blocked. But it does not guarantees that all the updates have been
committed to storage on remote servers. So when all the instances
have done phase1 barrier successfully, the MGS will notify all
instances to do the phase2 barrier as following:

Every barrier instance will call dt_sync() to make all async
transactions to be committed locally.

LU-8582 tests: skip sanity test_255a for interop

Move the sanity.sh test_255a version check to the start of the test
instead of after some of the ladvise functionality is tested.

That said, there is still an issue here, because the client shouldn't
hang indefinitely if the server is returning -EOPNOTSUPP, in the case
where a new client/lfs is connecting to an old OSS, and that issue is
not addressed by this patch.

LU-9098 lnet: Move lnet_routes.conf to /etc

lustre_routes_config now skips lines which are blank or
have a first non-whitespace character of #. This enables
comments to be placed in /etc/lnet_routes.conf. Also,
provide a sample lnet_routes.conf.

The SysV lnet script now expects lnet_routes to be
in /etc. Updated docs to reflect the new location.

LU-8139 ofd: allow brw_size with 'M' suffix

Allow specifying the 'M' suffix for the obdfilter.*.brw_size tunable
to maintain compatibility with original version of this tunable.

Fix sanity.sh test_101g() to only specify the 'M' suffix if this is
allowed by the server version, otherwise specify only the number.
Check both read and write RPC counts in the test, and also 8MB RPCs.

Clean up test_101g() to remove duplicate code, and only change the
brw_size parameter and remount the clients if the current brw_size
is not large enough.  Calculate the number of pages correctly for
systems with different PAGE_SIZE.
