On RHEL 7 I see the following error when trying to patch meminfo.o:
cp: cannot stat ‘/home/user/.kpatch/obj/fs/proc/.tmp_meminfo.o’: No such file or directory
It turns out that on RHEL 7, a given object foo.o is compiled as
.tmp_foo.o before then being linked as foo.o. I have no idea why. The
fix is to record .tmp_foo.o as foo.o in the changed_objs file.
