   1 # Linux kernel backports package
   2
   3 This package provides backport support for drivers from newer kernels
   4 down to older kernels. It currently backports the following subsystems:
   5
   6   * Wireless
   7   * NFC
   8   * WWAN

  28 # Backporting preference for EXPORT_SYMBOL_GPL() and proprietary drivers
  29
  30 This framework was designed by intent since its inception *only* for upstream
  31 Linux kernel drivers to avoid excuses about the difficulty to support upstream
  32 Linux kernel development while also supporting users on older kernels. To
  33 ensure the intent is respected currently all symbols that we do work on to
  34 backport are exported via EXPORT_SYMBOL_GPL() as we do work to backport them
  35 for the supported kernels. By using EXPORT_SYMBOL_GPL() we make it *clear* that
  36 if you use the backported symbols your software *is* considered derivative
  37 works of the Linux kernel.
