Subject: config: kernel: Add support for configuring BTRFS to be built-in
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b51abacb5fd465e5ce4329ec27ac516b5a2b83b9;p=openwrt%2Fstaging%2Fwigyori.git

config: kernel: Add support for configuring BTRFS to be built-in

Add the KERNEL_BTRFS_FS config option so that targets can select
whether BTRFS support must be built-in.

Select this option (alongside KERNEL_BTRFS_FS_POSIX_ACL) from the
layerscape/armv8_64b subtarget instead of enabling it in
target/linux/layerscape/armv8_64b/config-* files.

Move disabling of CONFIG_BTRFS_FS_CHECK_INTEGRITY into generic configs.

This makes it possible for OpenWRT to be built with built-in BTRFS
support on specific boards, instead of whole targets.
