checkpatch complains about positive return values of poll functions. Example: WARNING: return of an errno should typically be negative (ie: return -EPOLLIN) + return EPOLLIN; Poll functions return positive values. The defines for the return values of poll functions all start with EPOLL, resulting in a number of false positives. An often used workaround is to assign poll function return values to variables and returning that variable, but that is a less than perfect solution. There is no error definition which starts with EPOLL, so it is safe to omit the warning for return values starting with EPOLL.

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.
