On a senario like writing out the first dirty page of the inode as the inline data, we only cleared dirty flags of the pages, but didn't clear the dirty tags of those pages in the radix tree. If we don't clear the dirty tags of the pages in the radix tree, the inodes which contain the pages will be marked with I_DIRTY_PAGES again and again, and writepages() for the inodes will be invoked in every writeback period. As a result, nothing will be done in every writepages() for the inodes and it will just consume CPU time meaninglessly.

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.
