In the Linux dcache a directory only ever has one dentry, so d_splice_alias() can be used by ll_splice_alias() for directories. It will find the one dentry whether it is DCACHE_DISCONNECTED or IS_ROOT() or d_lustre_invalid(). Separating out the directories from non-directories will allow us to simplify the non-directory code.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
