[PATCH] kexec: should use uchunk for user buffer increasing
From: yang.zhang
Date: Tue Jan 30 2024 - 05:18:53 EST
From: "yang.zhang" <yang.zhang@xxxxxxxxxxxx>
Because of alignment requirement in kexec-tools, there is
no problem for user buffer increasing when loading segments.
But when coping, the step is uchunk, so we should use uchunk
not mchunk.
