This function already has multiple exit points, so there's no harm adding another. Although it looks odd to return directly in a function which takes a lock, we've actually just dropped the mmap_sem in this code, so there's really no reason to go via a label. And it means we can drop the unhelpfully named out2 label. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> [mpe: Rewrite change log] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
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.
