The section "19) Editor modelines and other cruft" in
Documentation/process/coding-style.rst clearly says, "Do not include any
of these in source files."
I recently receive a patch to explicitly add a new one.
Let's do treewide cleanups, otherwise some people follow the existing code
and attempt to upstream their favoriate editor setups.
It is even nicer if scripts/checkpatch.pl can check it.
If we like to impose coding style in an editor-independent manner, I think
editorconfig (patch [1]) is a saner solution.

dio entry will only do truncate in case of ORPHAN_NEED_TRUNCATE. So do
not include it when doing normal orphan scan to reduce contention.

Once dio crashed it will leave an entry in orphan dir. And orphan scan
will take care of the clean up. There is a tiny race case that the same
entry will be truncated twice and then trigger the BUG in
ocfs2_del_inode_from_orphan.

Add functions to add inode to orphan dir and remove inode in orphan dir.
Here we do not call ocfs2_prepare_orphan_dir and ocfs2_orphan_add
directly. Because append O_DIRECT will add inode to orphan two and may
result in more than one orphan entry for the same inode.

reflink is a very complicated process, so it can't be integrated
into one transaction. So if the system panic in the operation, we
may leave a unfinished inode in the destication directory.
So we will try to create an inode in orphan_dir first, reflink it
to the src file and then move it to the destication file in the end.
In that way we won't be afraid of any corruption during the reflink.
This patch adds 2 functions for orphan_dir operation:
1. Create a new inode in orphand dir.
2. Move an inode to a target dir.
Note:
fsck.ocfs2 should work for us to remove the unfinished file in the
orphan_dir.

The code for adding, removing, deleting directory entries was splattered all
over namei.c. I'd rather have this all centralized, so that it's easier to
make changes for inline dir data, and eventually indexed directories.
None of the code in any of the functions was changed. I only removed the
static keyword from some prototypes so that they could be exported.

Many struct inode_operations in the kernel can be "const". Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data. In addition it'll catch accidental writes at compile time to
these shared resources.

This is mostly a search and replace as ocfs2_journal_handle is now no more
than a container for a handle_t pointer.
ocfs2_commit_trans() becomes very straight forward, and we remove some out
of date comments / code.
