| |
Hello,
This patchset plugs all memory leaks that are due to expressions not being freed, when parsing the x86 Kconfigs (and likely the other ARCHes too). 336 KB are leaked in total.
Together with the memory leaks plugged in the parser in https://lkml.org/lkml/2017/10/8/126, this plugs all memory leaks when parsing the x86 Kconfigs.
As a reminder, the parsers can be rebuilt like this:
$ make REGENERATE_PARSERS=1 conf
Here's an easy way to run Valgrind on menuconfig (nothing seems to look at KERNELVERSION, so just set it to avoid a warning):
$ ARCH=x86 SRCARCH=x86 KERNELVERSION=4.14.0-rc2 valgrind --leak-check=full scripts/kconfig/mconf Kconfig
Cheers, Ulf
