Ok, here is the current failure with dwarves 1.21 on 5.12:

[ 2548s]   LD      vmlinux
[ 2557s]   BTFIDS  vmlinux
[ 2557s] FAILED unresolved symbol vfs_truncate
[ 2558s] make[1]: ***
[/home/abuild/rpmbuild/BUILD/kernel-kvmsmall-5.12.0/linux-5.12/Makefile:1213:
vmlinux] Error 255

Any idea where this one is coming from?

Thanks

Michal
