If an invalid option is given for "test_suspend=<option>", the entire string is added to init's environment, so return 1 instead of 0 from the __setup handler. Unknown kernel command line parameters "BOOT_IMAGE=/boot/bzImage-517rc5 test_suspend=invalid" and Run /sbin/init as init process with arguments: /sbin/init with environment: HOME=/ TERM=linux BOOT_IMAGE=/boot/bzImage-517rc5 test_suspend=invalid Fixes: 2ce986892faf ("PM / sleep: Enhance test_suspend option with repeat capability") Fixes: 27ddcc6596e5 ("PM / sleep: Add state field to pm_states[] entries") Fixes: a9d7052363a6 ("PM: Separate suspend to RAM functionality from core") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Reported-by: Igor Zhbanov <i.zhbanov@omprussia.ru> Link: lore.kernel.org/r/64644a2f-4a20-bab3-1e15-3b2cdd0defe3@omprussia.ru Signed-off-by: Rafael J.

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.
