/* This file contains the definitions for what kernel features need backports
 * for a given kernel. It targets only the standard stable kernel releases.
 * It must check only LINUX_VERSION_CODE and assume the kernel is a standard
 * release, and not a custom distribution.
 *
 * It must define HAVE_<FLAG> and NEED_<FLAG> for features. It must not
 * implement any backports, instead leaving the implementation to the
 * kcompat_impl.h header.
 *
 * If a feature can be easily implemented as a replacement macro or fully
 * backported, use a NEED_<FLAG> to indicate that the feature needs
 * a backport. (If NEED_<FLAG> is undefined, then no backport for that feature
 * is needed).
 *
 * If a feature cannot be easily implemented in kcompat directly, but
 * requires drivers to make specific changes such as stripping out an entire
 * feature or modifying a function pointer prototype, use a HAVE_<FLAG>.
