As it is, short copy in write() to append-only file will fail to truncate the excessive allocated blocks. As the matter of fact, all checks in ufs_truncate_blocks() are either redundant or wrong for that caller. As for the only other caller (ufs_evict_inode()), we only need the file type checks there.

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.
