[PATCH] kbuild, link-vmlinux: Don't delete output files with make -i

[PATCH] kbuild, link-vmlinux: Don't delete output files with make -i

[Jiri Slaby]

From: Andi Kleen <andi@firstfloor.org>

make -i is useful to see output files which normally get deleted on an
error.  Make this work with link-vmlinux.sh too. Don't delete the output
files on error when make -i is used.

I am afraid you missed this commit:



commit 51eb95e2da41802454f48b9afeb4d96a77295035
Author: Andi Kleen <ak@linux.intel.com>
Date:   Tue May 4 20:35:27 2021 -0700

    kbuild: Don't remove link-vmlinux temporary files on exit/signal

    Keep them around until they are cleaned up by make clean. This
    uses a bit more disk space, but makes it easier to debug any
    problems with the kernel link process.

Oops, thanks a lot for pointing out. We are going through the Andi's LTO 
patches and this went unnoticed as it was changed differently (and 
rebase succeeded). Now dropped from the queue.

thanks,
