Previously, /proc/fs/ext4/<dev>/options would only show binary options if they were set (1 in the options bit mask). E.g. it would show "grpid" if it was set, but it would not show "nogrpid" if grpid was not set. This seems sensible, but when an option is absent from the file, it can be hard for the unfamiliar to know what is being used. E.g. if there isn't a (no)grpid entry, nogrpid is in effect. But if there isn't a (no)auto_da_alloc entry, auto_da_alloc is in effect. If there isn't a (minixdf|bsddf) entry, it turns out bsddf is in effect. It all depends on how the option is implemented. It's clearer to be explicit, so print the corresponding option regardless of whether it means a 1 or a 0 in the bit mask. Note that options which do not have an explicit disable option aren't indicated as being disabled even with this change (e.g. dax).

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.
