rpm name from "rpm -q kernel-modules".

We also add "|| true" to the last line of the %preun scriptlet so that
failure does not aport installation.

We can create a jira to make the log and yml files consistant, but the reality
is that the yml files have a short life and are only used to send to Maloo.

This change will allow automated posting of results and automated testing to
begin.

1. Carries out the above using hostname -s [Thanks Andreas]
2. Adds in a quick change so that LUSTRE_BUILD in yaml.sh can be a reference to
the source rather than just the lustre version string which is recorded and
written to the yaml anyway as LUSTER_VERSION

Additionally a couple of other changes sneaked in.

1. Allows the review information to be applied to the yaml output file
by way of exporting the variable CODE_REVIEW_YAML to be a yaml description
for maloo

2. The addition of a couple of fixes to make the permissions for yaml
files be allow-all. This permissions are bracketed and so do not change any
other parts of the code.

LU-481 Don't store 'transient' page in radix tree

- We currently store both 'transient' page and inode page in the
  same radix tree, which will cause trouble for the race handling
  of concurrent dio and buffered read, imagine the following case:

  dio created a 'transient' page for a given file offset in the
  radix tree, while a concurrent buffered read on the same offset
  happened, the reader will try to find the exsting cached page by
  searching the radix tree, however, the 'transient' page is found,
  and the read will fail for -EBUSY at the end.

  To make the situation worse, there are two level of radix trees for
  a give file page (object and sub-object), above race can happen
  in both levels and we have to make sure page type consistence
  between these two levels.

  Actually, it doesn't make sense to store these disposable 'transient'
  page in the radix tree, so we just remove them in this patch.

- In cl_page_alloc(), if the coo_page_init() fails, we should call
  cl_page_delete0() to break the linkage between vmpage and cl_page
  before calling cl_page_free().

LU-419 mkfs: fix default ext4 filesystem tuneables

Enable the "64bit" feature flag for filesystems over 16TB (2^32
blocks, really).  Otherwise, the user needs to specify "-t ext4"
explicitly for such filesystems, or otherwise specify all of the
mke2fs features explicitly to format huge filesystems.

Porting the LU-255 patch to b1_8, I also wanted to make sure that
the new default inode ratio for OSTs was not too aggressive.  While
Lustre filesystems generally have average file sizes over 1MB, in
some limited number of cases the user filesystem statistics sent to
lustre-discuss had filesystems with an ratio of 600kB/inode region.

While the average FILE size may be > 1MB/file, if the default LOV
striping is 2 or 4 stripes/file then there may be a large number of
zero-length inodes on the OST that will be allocated and need space.

Reduce the default inode ratio to previously changed in commit
eb012d4a10208b26c2d3e795a90f1bb07dde6d91 from 1MB/inode down to
512kB/inode for filesystems between 4TB and 16TB, and only go up to
1MB/inode for filesystems over 16TB.  Since there are no existing
filesystems that large, there is no firm expectation for how many
inodes should be created for such filesystems, so this is safer.

LU-397 Set 'lsr_flags' as 'LU_SEQ_RANGE_MDT' for old 2.0 client

Lustre 2.x introduces server identifier into lu_seq_range to distinguish
MDT and OST fids. But for old 2.0 client, it does not specify such
identifier/flags. So use 'OBD_CONNECT_SEQ_RANGE' to distinguish whether
it is old 2.0 client or not. For old 2.0 client, set the 'lsr_flags' as
'LU_SEQ_RANGE_MDT' by default.

LU-395 Fix obd_zombie_barrier()

The obd_zombie_barrier() is waiting for obd_zombie_export list is empty
and exit, but export may be not yet destroyed. This produces race between export
destroying and other cleanups like lut_fini()

The patch introduces zombies_in_destroy variable which is counter, and
obd_zombie_barrier is checking it.

Due to bug 13698, the lfsck part of the lfsck.sh test script was
disabled by default.   After the fixes in LU-113 were landed, lfsck

lfsck instead of silently skipping it unless LFSCK_SKIP=no is set.

LU-399 do not use mke2fs -E resize for large LUNs

The mo_device_size variable is in units of kB, so take this into
account correctly when computing the filesystem block count.
The "-E resize" option is being used to align metadata on 1MB IO
boundaries, but it does not work for devices larger than 2^32 blocks.

A better long-term solution is to fix mke2fs so that it does this
alignment itself based on the s_raid_stride value.
