Subject: migrate_pages: modify max number of pages to migrate in batch
Date: Mon, 24 Jun 2024 12:51:20 +0800
We restrict the number of pages to be migrated to no more than
HPAGE_PMD_NR or NR_MAX_BATCHED_MIGRATION, but in fact, the number of pages
to be migrated may reach 2*HPAGE_PMD_NR-1 or 2
*NR_MAX_BATCHED_MIGRATION-1, it's not in inconsistent with the context.
Please refer to commit 42012e0436d4 ("migrate_pages: restrict number of
pages to migrate in batch").
