From: root <root@xxxxxxxxxxxxxxxxxxxxxxxxxx> As more complicated capsule kernel format occurs like zboot, where the compressed kernel is stored as a payload. The straight forward decompression can not meet the demand. As the first step, on aarch64, reading in the kernel file in a probe method and decide how to unfold the content by the method itself. This series consists of two parts [1/5], simplify the current aarch64 image probe [2-5/5], return the kernel fd by the image load interface, and let the handling of zboot image built on it. (Thanks for Dave Young, who contributes the original idea and the code) To ease the review, a branch is also available at https://github.com/pfliu/kexec-tools.git branch zbootV7 To: kexec@xxxxxxxxxxxxxxxxxxx Cc: Dave Young <dyoung@xxxxxxxxxx> Cc: horms@xxxxxxxxxxxx Cc: ardb@xxxxxxxxxx Cc: jeremy.linton@xxxxxxx --- v6 -> v7 Fix the included file issue in dist v5 -> v6 introduce kexec_info.kernel_fd and return the fd through image load interface.
