Resolved Date: Mar 21, 2017
Found In Version: 7.0.0.22
Fix Version: 7.0.0.24
Severity: Standard
Applicable for: Wind River Linux 7
Component/s: Kernel
I created an issue ( LIN7-7546 ) because there was a problem adding a filesystem, the patch worked well, however the filesystem was added as a Module and after the compiling part the linker couldn't find do_falloc symbols.
Steps to reproduce:
================
Create a project using these configure options
configure --enable-board=ti-66ak2xxx --enable-rm-oldimgs=yes --enable-kernel=preempt-rt --enable-bootimage=cpio,ubifs --with-mkubifs-args="-F -m 2048 -e 126976 -c 8015" --enable-rootfs=glibc_std
Then add aufs using menuconfig
$make linux-windriver.menuconfig
The config file of kernel should have aufs options with the values below
CONFIG_AUFS_FS=m
CONFIG_AUFS_BRANCH_MAX_127=y
# CONFIG_AUFS_BRANCH_MAX_511 is not set
# CONFIG_AUFS_BRANCH_MAX_1023 is not set
# CONFIG_AUFS_BRANCH_MAX_32767 is not set
CONFIG_AUFS_SBILIST=y
# CONFIG_AUFS_HNOTIFY is not set
# CONFIG_AUFS_EXPORT is not set
# CONFIG_AUFS_FHSM is not set
# CONFIG_AUFS_RDU is not set
# CONFIG_AUFS_SHWH is not set
# CONFIG_AUFS_BR_RAMFS is not set
# CONFIG_AUFS_BR_FUSE is not set
CONFIG_AUFS_BDEV_LOOP=y
# CONFIG_AUFS_DEBUG is not set
Then apply the patch on LIN7-7546
Then build the kernel with
$make linux-windriver
The error output was:

I created a patch for that and it works as expected, after that the build is successful. Can you please validate it?
