The source is associated with a source inode, and the target is associated with a target inode. A list is generated of the one of the source or target inodes followed by another of the source or target inodes according to inode numbers identifying the source and target inodes. A first determination includes determining that the one inode is the source inode and the other inode is the target inode. When the first determination is made, a read rename lock is acquired for the source inode, followed by a write rename lock for the target inode, followed by a read inode lock for the source inode, followed by a write inode lock for the target inode. After the locks have been acquired, a chunk map of the source inode is copied to the target inode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Deadlock-free locking for consistent and concurrent server-side file operations in file systems","description":"A request is received to copy a file from a source to a target in a file system.
