Currently we don't allow direct I/O on encrypted regular files, so in such cases we return 0 early in ext4_direct_IO(). There was also an additional BUG_ON() check in ext4_direct_IO_write(), but it can never be hit because of the earlier check for the exact same condition in ext4_direct_IO(). There was also no matching check on the read path, which made the write path specific check seem very ad-hoc. Just remove the unnecessary BUG_ON().

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.
