Hi Jeremy, Thanks for sharing this. When I get your series, my series is close to end, so just post it. My 2/5 is identical to your 4/4, and can be dropped. My 5/5 is similar to your 2/4, which can be dropped either. The main difference is about the image probe method. Since the introduction of zboot format, it is not proper any more to call the slurp_decompress_file() function once before attempting to call various possible probes. So my series scatters the slurp_decompress_file() into each probe, and return two factors: the kernel fd which is used by sys_kexec_file_load and the parsed kernel buf, which is used later by the image probe function.
