[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The patch titled
     Subject: kexec: remove never used member destination  in kimage
has been removed from the -mm tree.  Its filename was
     kexec-remove-never-used-member-destination-in-kimage.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Baoquan He <bhe@xxxxxxxxxx>
Subject: kexec: remove never used member destination  in kimage

struct kimage has a member destination which is used to store the real
destination address of each page when load segment from user space buffer
to kernel.  But we never retrieve the value stored in kimage->destination,
so this member variable in kimage and its assignment operation are
redundent code.

I guess for_each_kimage_entry just does the work that kimage->destination
is expected to do.

So in this patch just make a cleanup to remove it.
