ocfs2_create_inode_in_orphan() is used by reflink to create the newly
reflinked inode simultaneously in the orphan dir. This allows us to easily
handle partially-reflinked files during recovery cleanup.

We have a problem though - the orphan dir stringifies inode # to determine
a unique name under which the orphan entry dirent can be created. Since
ocfs2_create_inode_in_orphan() needs the space allocated in the orphan dir
before it can allocate the inode, we currently call into the orphan code:

       /*
        * We give the orphan dir the root blkno to fake an orphan name,
        * and allocate enough space for our insertion.
        */
       status = ocfs2_prepare_orphan_dir(osb, &orphan_dir,
                                         osb->root_blkno,
                                         orphan_name, &orphan_insert);

Using osb->root_blkno might work fine on unindexed directories, but the
orphan dir can have an index.  When it has that index, the above code fails
to allocate the proper index entry.  Later, when we try to remove the file
from the orphan dir (using the actual inode #), the reflink operation will
fail.

To fix this, I created a function ocfs2_alloc_orphaned_file() which uses the
newly split out orphan and inode alloc code to figure out what the inode
block number will be (once allocated) and then prepare the orphan dir from
that data.

We do this because ocfs2_create_inode_in_orphan() wants to order locking of
the orphan dir with respect to locking of the inode allocator *before*
making any changes to the directory.

This allows code which needs to know the eventual block number of an inode
but can't allocate it yet due to transaction or lock ordering. For example,
ocfs2_create_inode_in_orphan() currently gives a junk blkno for preparation
of the orphan dir because it can't yet know where the actual inode is placed
- that code is actually in ocfs2_mknod_locked. This is a problem when the
orphan dirs are indexed as the junk inode number will create an index entry
which goes unused (and fails the later removal from the orphan dir).  Now
with these interfaces, ocfs2_create_inode_in_orphan() can run the block
group search (and get back the inode block number) *before* any actual
allocation occurs.

Do this by splitting the bulk of the function away from the inode allocation

The patch is to fix the regression bug brought from commit 6b933c8e...( 'ocfs2:
Avoid direct write if we fall back to buffered I/O'):

http://oss.oracle.com/bugzilla/show_bug.cgi?id=1285

The commit 6b933c8e changed __generic_file_aio_write
to generic_file_buffered_write, which didn't call filemap_{write,wait}_range to  flush
the pagecaches when we were falling O_DIRECT writes back to buffered ones. it did hurt
the O_DIRECT semantics somehow in extented odirect writes.

This patch tries to guarantee O_DIRECT writes of 'fall back to buffered' to be correctly
flushed.

We cannot call grab_cache_page() when holding filesystem locks or with
a transaction started as grab_cache_page() calls page allocation with
GFP_KERNEL flag and thus page reclaim can recurse back into the filesystem
causing deadlocks or various assertion failures. We have to use
find_or_create_page() instead and pass it GFP_NOFS as we do with other
allocations.

We were setting ac->ac_last_group in ocfs2_claim_suballoc_bits from
res->sr_bg_blkno.  Unfortunately, res->sr_bg_blkno is going to be zero under

For local mounts, ocfs2_read_locked_inode() calls ocfs2_read_blocks_sync() to
read the inode off the disk. The latter first checks to see if that block is
cached in the journal, and, if so, returns that block. That is ok.

But ocfs2_read_locked_inode() goes wrong when it tries to validate the checksum
of such blocks. Blocks that are cached in the journal may not have had their
checksum computed as yet. We should not validate the checksums of such blocks.

commit 8262bb85da allocated the inode integrity struct (iint) before any

the counters updated. This patch updates the counters, whether or not IMA
has been initialized, to resolve 'imbalance' messages.

This patch fixes the bug as reported in bugzilla: 15673.  When the i915
is builtin, the ring_buffer is initialized before IMA, causing the
imbalance message on suspend.

The locking for profile namespace removal is wrong, when removing a

As per Dan Carpenter <error27@gmail.com>
  If we have a ns name without a following profile then in the original
  code it did "*ns_name = &name[1];".  "name" is NULL so "*ns_name" is
  0x1.  That isn't useful and could cause an oops when this function is
  called from aa_remove_profiles().

Beyond this the assignment of the namespace name was wrong in the case
where the profile name was provided as it was being set to &name[1]
after name  = skip_spaces(split + 1);

Move the ns_name assignment before updating name for the split and
also add skip_spaces, making the interface more robust.
