treewide: remove editor modelines and cruft 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.

ocfs2: do not include dio entry in case of orphan scan 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.

[PATCH] mark struct inode_operations const 2 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.

ocfs2: add functions to add and remove inode in orphan dir 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.

ocfs2: Create reflinked file in orphan dir. 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. Signed-off-by: Tao Ma <tao.ma@oracle.com>
