On one Customer site, we hit following deadlock:

Thread 1:
ofd_object_punch
 osd_punch
  ldiskfs_truncate
   ldiskfs_inode_attach_jinode
     ...
     do_try_to_free_pages
      lu_cache_shrink
       mutex_lock -->try to hold @lu_sites_guard

kswapd thread2:
kthread
 shrink_slab
  lu_cache_shrink
    mutex_lock ---->hold already.
     ...
     dqget
      ldiskfs_acquire_dquot
       jbd2__journal_start-->blocked to wait for more credits.

Thread3:
kthread
 kjournald2
  jbd2_journal_commit_transaction-->blocked to wait Thread2 finished,
				 since Thread1 add a handle into transaction.

So deadlock happens because of Thread1 wait Thread2, Thread2 wait Thread3..
but Thread3 wait Thread1....

This problem still exists even we have switched @lu_sites_guard
into a read/write lock, sine we hold write lock at lu_cahce_shrink().

Fixed the problem by making ldiskfs_inode_attach_jinode() use
GFP_NOFS.

See comments in ext4_free_clusters_after_init:
/* Return the number of free blocks in a block group.  It is used when
 * the block bitmap is uninitialized, so we can't just count the bits
 * in the bitmap. */
So extra check we enhanced here is wrong if this block group
bitmap is uninitialized, since we only check bitmaps here.

Further, Looking at EXT4_BG_BLOCK_UNINIT clear codes, Kernel
will reinit free_clusters_count when tried to clear the flag, so
extra check for uninited block bitmaps dosen't make much sense.

Let's skip uninited block bitmap check if EXT4_BG_BLOCK_UNINIT
is set, whatever free count group desc recorded is untrustable somehow

When initializes (reformat) the filesystem, the number of
free blocks in the group descriptor is calculated via the
ext2fs_reserve_super_and_bgd() (e2fsprogs). As commented
in such function: "This is not necessarily the case when
the flex_bg feature is enabled, so callers should take care!".

So it is normal that we may find the block group descriptor
that has LDISKFS_BG_BLOCK_UNINIT flag but with 0 free blocks.
The ldiskfs_mb_check_ondisk_bitmap() should NOT report error
for such block group, instead, skip the check directly.

Add the new ldiskfs patch series file ldiskfs-3.10-rhel7.3.series which
supports the RHEL7.3 kernel.  Three patch files needed contextual updates
to allow them to apply.

Note that the new RHEL7.3 kernel contains a backport of the
upstream linux kernel commit 923ae0ff9250430133b3310fe62c47538cf1cbc1,
which introduces DAX to ext4.  This adds the flag EXT4_MOUNT_DAX
with value 0x00200.  This conflicted with ext4-data-in-dirent.patch's
EXT4_MOUNT_DIRDATA flag value.  Therefore, for RHEL7.3 the value of the
EXT4_MOUNT_DIRDATA flag is changed to 0x00002.

The ext4-corrupted-inode-block-bitmaps-handling-patches.patch needed
updating for two problems:

In ext4_validate_block_bitmap(), the patch removes the
struct ext4_group_info *grp declaration.  The upstream kernel now
has the following at the beginning of the function:

        if (buffer_verified(bh) || EXT4_MB_GRP_BBITMAP_CORRUPT(grp))
                return;

The declaration/definion of grp is reintroduced to address that
use.

When we hit Lustre crash, e2fsck always complains of Quota
accounting mismatch, and sometimes differences are huge.

The problem is that we don't journal quota updates properly, and
with current codes quota files will be only journaled when syncing
the filesystem, which only happens by sync() call or unmount.
