Subject: [PATCH 0/3] page table check fixes and cleanups
Date: Thu, 20 Jan 2022 04:25:10 +0000 [thread overview]
Message-ID: <20220120042513.1648831-1-pasha.tatashin@soleen.com> (raw)
Two fixes:
mm/debug_vm_pgtable: remove pte entry from the page table
- remove a pte entry from the page table at the end of debug_vm_pgtable pte test
mm/page_table_check: check entries at pud and pmd levels
- check pmd and pud levels in page_table_check for regular entries not only for
huge pages when entries are replaced or cleared.
