zboot image consists of zboot_header and Image.gz. And the compressed
payload should be located and parsed with extra effort. Most of
important, the kernel can only work with Image, so the final fd should
point to a temporary file, which contains Image.

Hi Pingfan,
There seem to be:
a) other places where slurp_decompress_file() is called and;
b) other places where do_kexec_file_load()
22 matches
