Re: [Crash-utility] [PATCH v3 3/3] memory_driver: Support overriding kernel directory
Hi Mathias,
thank you for the patch set, looks good.
On 2023/09/28 18:19, Mathias Krause wrote:
Support compiling the module against a different kernel version than
the
currently running one by allowing to set either KVER or KDIR variables
on the make commandline.
Also modernize the makefile slightly and make use of the kernel's
'clean' target to ensure to remove all generated files.

Only one question, is this for to build the module in a customized
kernel tree?
Thanks,
