LU-5549 mdc: cl_default_mds_easize not refreshed

The client_obd::cl_default_mds_easize field should track the largest
observed EA size advertised by the MDT, subject to a reasonable upper
bound.  The MDC uses cl_default_mds_easize to calculate the initial
size of request buffers.  The default value should be small enough to
avoid wasted memory and excessive use of vmalloc(), yet large enough
to accommodate the common use case.

In the current code, the default value is only updated if
client_obd::cl_max_mds_easize is strictly less than
mdt_body::mbo_max_mdsize. This condition is almost never met, because
client_obd::cl_max_mds_easize is computed at client mount-time based
on the number of OSTs in the filesystem, so the MDT won't ever observe
and advertise an EA size larger than that.

As a result, client_obd::cl_default_mds_easize indefinitely retains
its initial value, which is computed at client mount-time based on
the filesystem's default stripe width. Any getattr() requests for
widely striped files will consequently allocate a request buffer
that is too small, forcing reallocations on both the client and
server side. To avoid this, update client_obd::cl_default_mds_easize
independently of the value of client_obd::cl_max_mds_easize.

In addition, this patch includes these changes:

- Add comments to the client_obd structure to clarify what the
  cl_{default,max}_mds_{cookie,ea}size values mean.

- Prevent mdc_get_info() from storing uninitialized data in
  client_obd::cl_max_mds_cookiesize.

- Use 4096 as an upper bound for the default values.  The former
  bound of PAGE_CACHE_SIZE is too large on 64k-page platforms
  (i.e. PPC), so it fails to prevent the vmalloc() spinlock
  contention described in LU-3338. The new value was chosen to
  be large enough to accommodate common use cases while staying
  well below the 16k threshold at which allocations start using
  vmalloc().

- Add test case 27E to ./lustre/tests/sanity.sh.

LU-6084 ptlrpc: prevent request timeout grow due to recovery

Patch fixes the issue with growing request timeout which occured
after commit 1d889090 for LU-5079. While commit itself is correct,
it reveals another issue. If request is being processed for a long
time on server then client adaptive timeouts will adapt to that
after receiving reply and new requests will have bigger timeout.
Another problem is that server AT history is corrupted by recovery
request processing time which not pure service time but includes
also waiting time for clients to recover.

Patch prevents the AT stats update from early replies on client and
from recovering requests processing time on server.
The ptlrpc_at_recv_early_reply() still updates the current request
timeout as asked by server, but don't include this into AT stats.
The real reply will bring that data from server after all.

for the case of upgrading from old OST device, you can enable it

LU-6063 kernel: use proper flags for call_usermodehelper

When a parameter is permanently changed on the MGS the
MGS send a changelog packet to the proper nodes that
are affected by the change. Once the nodes receive the
change they then call the userland utility lctl to
change its local value. When calling a userland
application from the kernel you specify a flag to
control the interaction with the application. Originally
by default the flag was set to 0 which is UMH_NO_WAIT
which meant lctl was being called asynchronously. In
older kernels this was fine since UHM_NO_WAIT and
UHM_WAIT_PROC had nearly the same logic. This changed
with newer kernels which broke updating our parameters.
Plus doing a UHM_NO_WAIT doesn't report back a error
if something goes wrong with lctl. The fix is to set
the flag to UHM_WAIT_PROC so kernel space waits until
lctl has finished and we get a proper error code if
something does go wrong with lctl. Secondly the patch
uses the proper flag name instead of a number for the
use of call_usermodehelper in mdt_identity.c so the
code is more readable.

LU-5820 lfsck: use multiple namespace LFSCK trace files

The namespace LFSCK uses trace file to record the FID of the object
that has multiple hard links, or has remote name entry, or contains
some uncertain inconsistency, and so on. Only single namespace LFSCK
trace file may be not efficient, especially when there are millions
of FIDs to be recorded. So use multiple namespace LFSCK trace files
and per trace file based semaphore to control the concurrent access
of the trace file.

For Lustre-2.x (x <= 6), the LFSCK used LFSCK_NAMESPACE_MAGIC_V1 as
the namespace trace file magic. When downgrade to such old release,
the old LFSCK will not recognize the new LFSCK_NAMESPACE_MAGIC_V2 in
the new trace file, then it will reset the whole LFSCK, and will not
cause start failure. The similar case will happen when upgrade from
such old release.

This patch also drops some repeated FID recording in the namespace
LFSCK trace file. Related FID should have been recorded in the trace
file via lfsck_namespace_exec_oit(), it is unnecessary to do that
again when scanning the directory.

LU-6147 lfsck: NOT purge object by OI scrub

Originally, when the OI scrub found some inconsistent FID mapping,
it will repair the FID mapping and ask others to reload the object
by purging such object. Such behavior may cause others to hang.
Because if the object corresponding to the FID has already been
established in RAM, and if some other holds the object's reference,
such as the LFSCK engine will hold the .lustre/lost+found/MDTxxxx,
then purging object will set LU_OBJECT_HEARD_BANSHEE on the object,
then the subsequent object find against such FID will be blocked
until the object's reference become zero and re-establish the object
in RAM. Unfortunately, if it is the object's reference holder tries
to find the same object, it will be blocked by itself for ever.

On the other hand, on the server side, the OI scrub will repair
the bad OI mappping, if the object is established in RAM before
its bad FID mapping repaired, then it must be marked as non-exist,
and should not be cached in RAM after the last reference released.

LU-5275 lprocfs: sync names to upstream kernel lustre client

When seq file handling was introduced to lustre we had to
create duplicate functions that handle a different type of
struct lprocfs_vars which was names struct lprocfs_seq_vars.
Now that lustre has moved to using only seq_file we can
rename the special *seq* functions and structures to what is
exactly in the upstream linux kernel. This helps to greatly
reduce the difference between upstream and the Intel branch.
