VFS_LINK(9) The Linux VFS VFS_LINK(9)NAMEvfs_link - create a new linkSYNOPSISint vfs_link(struct dentry * old_dentry, struct inode * dir, struct dentry * new_dentry, struct inode ** delegated_inode);ARGUMENTSold_dentry object to be linked dir new parent new_dentry where to create the new link delegated_inode returns inode needing a delegation breakDESCRIPTIONThe caller must hold dir->i_mutex If vfs_link discovers a delegation on the to-be-linked file in need of breaking, it will return -EWOULDBLOCK and return a reference to the inode in delegated_inode. The caller should then break the delegation and retry. Because breaking a delegation may take a long time, the caller should drop the i_mutex before doing so. Alternatively, a caller may pass NULL for delegated_inode. This may be appropriate for callers that expect the underlying filesystem not to be NFS exported.COPYRIGHTKernel Hackers Manual 3.10 June 2014 VFS_LINK(9)
