aufs: new kernel extension
Signed-off-by: Christian Stewart <christian@paral.in> [Atul: - Removed the duplicate conditional block. - Updated the license to GPLv2. - Removed the visibilty of package from menuconfig. - Removed dependencies. - Removed the comment. - Changed the name of variable from BR2_PACKAGE_AUFS_STANDALONE_VERSION to BR2_LINUX_KERNEL_EXT_AUFS_VERSION. - Removed the AUFS_INSTALL_STAGING and AUFS_INSTALL_TARGET variables. - Removed the BR2_PACKAGE_AUFS_3X and BR2_PACKAGE_AUFS_4X variables.] Signed-off-by: Atul Singh <atul.singh.mandla@rockwellcollins.com> [yann.morin.1998@free.fr: - do not fail on version check if aufs ext is disabled - check for empty version - squash aufs package and linux extension in one patch - fail if the kernel already has aufs support - simplify handling of version] Signed-off-by: Yann E. MORIN <yann.morin.1998@free.fr> [Thomas: - Fix the apply patch logic, it was using a non-existent AUFS_VERSION_MAJOR variable. BR2_PACKAGE_AUFS_SERIES is used instead.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
