The behavior of btrfs_delalloc_reserve_metadata depends on whether the inode we are allocating for is the freespace inode or not. As it stands if we are the free node we set 'flush' and 'delalloc_lock' variable to certain values. Subsequently we check the values of those vars and act accordingly. Instead, simplify things by having 1 if which checks whether we are the freespace inode or not and do any specific operation in either branches of that if. This makes the code a bit easier to understand, as an added bonus it also shrinks the compiled size: add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-17 (-17) Function old new delta btrfs_delalloc_reserve_metadata 1876 1859 -17 Total: Before=85966, After=85949, chg -0.02% No functional changes.

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.
