[Samba] Question Wiki Kernel support

[oeh univie edv lists]

Hey,

I refer to
https://wiki.samba.org/index.php/Operating_system_requirements/File_system_support#ext4

Wiki suggests:
Ensure that your kernel has the following options enabled: 
CONFIG_EXT4_FS_XATTR=y
CONFIG_EXT4_FS_SECURITY=y
CONFIG_EXT4_FS_POSIX_ACL=y

My debian 8.2 installation was installed from netinstall CD, all updates
applied. All my filesystems are ext4 and xattr and acl are not set, as
they are default for ext4.

19:06:17 # more /boot/config-3.16.0-4-amd64 | grep CONFIG_EXT4
CONFIG_EXT4_FS=m
CONFIG_EXT4_USE_FOR_EXT23=y
CONFIG_EXT4_FS_POSIX_ACL=y
CONFIG_EXT4_FS_SECURITY=y
# CONFIG_EXT4_DEBUG is not set

After install of package attr tests with setfattr and getfattr succeed. 

Do I still need CONFIG_EXT4_FS_XATTR=y ? If yes, how do I enable that in
the kernel?

kind regards, birgit
