init_ipath is called from a safe ioctl context and from scrub when printing an error. The protection is added for three reasons: * init_data_container calls vmalloc and this does not work as expected in the GFP_NOFS context, so this silently does GFP_KERNEL and might deadlock in some cases * keep the context constraint of GFP_NOFS, used by scrub * we want to use GFP_KERNEL unconditionally inside init_ipath or its callees Reviewed-by: Anand Jain <anand.jain@oracle.com> Signed-off-by: David Sterba <dsterba@suse.com> |

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.
