Subject: [PATCH v2 0/2] fix several contiguous memmap assumptions
Date: Wed, 30 Mar 2022 18:25:32 +0800 [thread overview]
Message-ID: <20220330102534.1053240-1-chenwandun@huawei.com> (raw)
v1 ==> v2:
remove page_nth
It isn't true for only SPARSEMEM configs to assume that a compound page
has virtually contiguous page structs, so use nth_page to iterate each
page.
Inspired by:
