LU-11455 build: Remove conflicting lustre and Lustre

Some systems (Mac) are still case insensivite under some conditions,
so having lustre and Lustre in the same directory causes problems.
Seperate all the resource agents into their own directory.

Another reason is we will also have random I/O error on

kmmpd could modify the content of the mmp block(e.g. setting

Using spare bits in iattr.ia_valid is not safe as the

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-8174 misc: name open file handles as such

In a number of places in the code, rename variables from "*_handle"
or "*_fh" to "*_open_handle" so that it is clear this is referencing
an open file handle rather than something else (e.g. a lock handle).

Also rename the confusingly-named mti_close_handle to mti_open_handle,
since this is referencing an open file handle, even if it is used at
close time to close the file.

   mfd_handle2mfd() -> mfd_open_handle2mfd()
   mdt_file_data.mfd_handle -> mfd_open_handle
   mdt_file_data.mfd_old_handle -> mfd_open_handle_old
   mdt_thread_info.mti_close_handle -> mti_open_handle
   mdt_body.mbo_handle -> mbo_open_handle
   mdt_io_epoch.mio_handle -> mio_open_handle

Change the resync code path to use a "lease_handle" to avoid confusion

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.

As connections are never deleted until the hash table is destroyed,

is also no need to enable automatic_shrinking.

Migrating directory contains stripes of both old and new layout, and

directory:
1. always create new file under new layout.
2. any operation that tries to create new file under old layout will
   be rejected, e.g., 'mv a <migrating_dir>/b', if b exists and is
   under old layout, this rename should fail with -EBUSY.
3. operations that access file by name should try old layout first,
   if file doesn't exist, then it will retry new layout, such
   operations include: lookup, getattr_name, unlink, open-by-name,
   link, rename.
4. according to rule 1, open(O_CREAT | O_EXCL) and create() will
   create new file under new layout, but they should check existing
   file in one transaction, however this can't be done for old
   layout, so check existing file under old layout on client side,
   then issue the open/create request to new layout.

Disable sanity 230d for ZFS backend because it will trigger lots of

LU-11301 target: add lock in sub_trans_stop_cb()

sub_trans st_committed and st_stopped flags take different bit of

LU-11303 out: clean up osp_update_rpc_pack() macro

The osp_update_rpc_pack() macro was using both an operation "name"
argument as well as an "opcode" argument, but totally ignoring the
"opcode" argument.  This allowed a caller in osp_attr_set() to pass
a non-existent opcode name to the function that was ignored.

The function also concatenated the passed name string to generate
a function name to be called (which supplied its own opcode value).
This name concatenation obscures the code functionality, since the
called functions are not actually referenced directly in the code.

Instead, pass the function name as the argument, and drop the opcode
completely.  This at least makes it possible to see where the function
is being called.  Change the macro to be upper-case, so that it is
more clear that it is a macro rather than a real function.  It would
be better to replace the macro with an actual function, but this is
not very practical due to the use of variable-length argument lists.

LU-8066 llite: use more private data in dump_pgcache

The dump_page_cache debugfs file allocates and frees an 'env' in each
call to vvp_pgcache_start,next,show.  This is likely to be fast, but
does introduce the need to check for errors.

It is reasonable to allocate a single 'env' when the file is opened,
and use that throughout.

So create 'seq_private' structure which stores the sbi, env, and
refcheck, and attach this to the seqfile.

Then use it throughout instead of allocating 'env' repeatedly.

LU-4684 migrate: migrate striped directory

Migrate striped directory in below steps:
1. create target object if needed: if source is directory, a
   target object is always created, otherwise if source is
   already located on the target MDT, or source still has
   link on source MDT, then skip creating.
a) if source is directory, detach source stripes and
   attach them to target.
b) migrate source xattrs to target.
c) if source is regular file, update PFID to target
   fid.
d) update fid to target for all links of source
2. update namespace
a) migrate dirent from source parent to target parent.
b) update linkea parent fid to target parent.
c) destroy source object.

This implementation improves following fields:
1. all involved objects are locked to avoid race.
2. directory migration doesn't migrate its dir entries, instead
   it's done in each sub file migration, this avoids timeout in
   migrating dir entries for large directory, and also avoids
   touching dir entries without lock.
3. file/dir is migrated in one transaction, so migrate recovery
   is the same as others.
4. migrating directory can be accessed (modifiable) like normal
   directory.
5. if migration of sub files under a directory fails, user can
   redo migrate to finish migration of this directory.

Disable migrate in racer.sh.

LU-10365 tests: set proper paths headers for sanity test 400a

For the case when /usr/include/lustre doesn't exist sanity test
400a attempts to use the lustre user land headers located in the
source tree. Some of the lustre user land headers are wrappers
around the UAPI headers so we need to include those paths as well.

A test move was done in the linux kernel that moved the UAPI headers
to their proper place. Errors were reported mainly due to
linux/types.h being missing. This could be the reason Ubuntu18 fails
the sanity 400a test.

Test-Parameters: trivial clientdistro=ubuntu1604 testlist=sanity envdefinitions=ONLY=400a

LU-11125 ofd: decrease message level

The "destroys_in_progress already cleared" message
in ofd_create_hdl() may be result of high load on OST
server prior failover. It is not an error, so decrease
its level to D_HA from D_ERROR.
