Subject: mm/page_isolation: don't pass gfp flags to isolate_single_pageblock()
Date: Tue, 3 Dec 2024 10:47:27 +0100
Patch series "mm/page_alloc: gfp flags cleanups for alloc_contig_*()", v2.
Let's clean up the gfp flags handling, and support __GFP_ZERO, such that we
can finally remove the TODO in memtrace code.
This patch (of 6):
The flags are no longer used, we can stop passing them to
isolate_single_pageblock().
