[lustre-discuss] Lustre 2.15.3: patching the kernel fails

[Jan Andersen]

My system: Debian 11, kernel version 5.10.0-13-amd64; I have the 
following source code:

I have downloaded the source code of lustre 2.15.3:

# git checkout 2.15.3
# git clone git://git.whamcloud.com/fs/lustre-release.git

- and I'm trying to build it, following 
https://wiki.lustre.org/Compiling_Lustre

I've got through 'autogen.sh' and 'configure' and most of 'make debs', 
but when it comes to patching:

cd linux-stage && quilt push -a -q

My best guess is that it is because the running kernel version doesn't 
exactly match the kernel source tree, but I can't seem to find that 
version. Am I right - and if so, where would I go to download the right 
kernel tree?
