commit 2d631bd58fe0ea3e3350212e23c9aba1fb606514 upstream. sys_foo() returns -512 (aka -ERESTARTSYS) => do_signal() sees 512 in r2 and 1 in r1. sys_foo() returns 512 => do_signal() sees 512 in r2 and 0 in r1. The former is restart-worthy; the latter obviously isn't.

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.
