If we bump i_version in ext4_mark_iloc_dity then we should be removing

followed by ext4_mark_inode_dirty.
How about the below patch. I also removed the i_version = 1 from
ext4_new_inode because we do the same in ext4_alloc_inode. I also added
the From: line.

Subject: [PATCH] This patch is on top of i_version_update_vfs.
The i_version field of the inode is set on inode creation and incremented when
the inode is being modified.
