    Code Block
    $ cd ~
$ rm -f ~/lustre-kernel-x86_64-lustre.patch
$ cd ~/lustre-release/lustre/kernel_patches/series
$ for patch in $(<"3.10-rhel7.series"); do \
      patch_file="$HOME/lustre-release/lustre/kernel_patches/patches/${patch}"; \
      cat "${patch_file}" >> "$HOME/lustre-kernel-x86_64-lustre.patch"; \
  done
$

  2. Copy the lustre kernel patch into RPM build tree

    Code Block
    # cp ~/lustre-kernel-x86_64-lustre.patch ~/kernel/rpmbuild/SOURCES/patch-3.10.0-lustre.patch

  3. Edit the kernel spec file by vi ~/kernel/rpmbuild/SPECSPECS/kernel.spec

    Find the line with 'find $RPM_BUILD_ROOT/lib/modules/$KernelVer' and insert following two lines below it

    cp -a fs/ext3/* $RPM_BUILD_ROOT/lib/modules/$KernelVer/build/fs/ext3 
    cp -a fs/ext4/* $RPM_BUILD_ROOT/lib/modules/$KernelVer/build/fs/ext4

    Find the line with '# empty final patch to facilitate testing of kernel patches' and insert following two lines below it

    # adds Lustre patches
    Patch99995: patch-%{version}-lustre.patch

    Find the line with 'ApplyOptionalPatch linux-kernel-test.patch' and insert following two lines below it

    # lustre patch
    ApplyOptionalPatch patch-%{version}-lustre.patch

    Find the line with '%define listnewconfig_fail 1' and change 1 to 0

    Save and close the spec file.


  4. Overwrite the kernel config file with ~/lustre-release/lustre/kernel_patches/kernel_configs/kernel-3.10.0-3.10-rhel7-x86_64.config

    Code Block
    echo '# x86_64' > ~/kernel/rpmbuild/SOURCES/kernel-3.10.0-x86_64.config
cat ~/lustre-release/lustre/kernel_patches/kernel_configs/kernel-3.10.0-3.10-rhel7-x86_64.config >> ~/kernel/rpmbuild/SOURCES/kernel-3.10.0-x86_64.config
