From: Christian Stewart Date: Sun, 17 Jul 2016 12:50:37 +0000 (+0200) Subject: aufs: new kernel extension X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=010588c1e169843bdca35c71789a16d0b6829bcb;p=buildroot.git aufs: new kernel extension Signed-off-by: Christian Stewart [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 [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 [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 --- diff --git a/linux/Config.ext.in b/linux/Config.ext.in index da1ebd26bc..5d5e7efbca 100644 --- a/linux/Config.ext.in +++ b/linux/Config.ext.in @@ -66,4 +66,56 @@ config BR2_LINUX_KERNEL_EXT_FBTFT https://github.com/notro/fbtft +# aufs-standalone +config BR2_LINUX_KERNEL_EXT_AUFS + bool "Aufs Filesystem Module patch" + select BR2_PACKAGE_AUFS + help + Aufs is split in two parts: a kernel part and a userspace + part.
