When mount with incorrect options such as: "mount -t bcachefs -o errors=back /dev/loop1 /mnt/bcachefs/". It rebacks the error "mount: /mnt/bcachefs: permission denied." cause bch2_parse_mount_opts returns -1 and bch2_mount throws it up. This is unreasonable. The real error message should be like this: "mount: /mnt/bcachefs: wrong fs type, bad option, bad superblock on /dev/loop1, missing codepage or helper program, or other error." Adding three private error codes for mounting error. Here are: - BCH_ERR_mount_option as the parent class for option error. - BCH_ERR_option_name represents the invalid option name. - BCH_ERR_option_value represents the invalid option value.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
