[PATCH v2 0/5] bootconfig: Fixes to bootconfig memory management

From: Masami Hiramatsu
Date: Tue Sep 14 2021 - 20:53:51 EST


Hello,

Here are the series of patches to fix bootconfig memory management issues.
>From v1, I added some more fixes and split a memory leak fix from freeing
unused memory patch.

[1/5] fixing kernel BUG issue on boot. Just rebased on the linus tree.
[2/5] Add new memblock leak fix in xbc_make_cmdline().
[3/5] Split from [4/5], fixing a memblock leak in setup_boot_config().
[4/5] Free unused memblock after boot. Use new memblock_free_ptr().
[5/5] Fix a tool build error caused by memblock_free_ptr().

And now I'm considering to move ownership of copied bootconfig data
to lib/bootconfig. That will make code simpler. But I also think fixing
bugs are urgent. So I send this series first.

Thank you,
