Subject: [PATCH 0/2] fix bug when calling kexec_load()
Date: Sun, 31 Oct 2021 02:31:58 +0800 [thread overview]
Message-ID: <20211030183200.51295-1-rongwei.wang@linux.alibaba.com> (raw)
Patch 1/2 mainly to fix the bug when calling kexec_load().
And a user case shown in commit log.
Patch 2/2 just make a very simple optimization, reducing
calls to page_address() in kexec_page_alloc().
Thanks!
