The patch titled
Subject: kmemcheck: stop using GFP_NOTRACK and SLAB_NOTRACK
has been removed from the -mm tree. Its filename was
kmemcheck-stop-using-gfp_notrack-and-slab_notrack.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: "Levin, Alexander (Sasha Levin)" <alexander.levin@xxxxxxxxxxx>
Subject: kmemcheck: stop using GFP_NOTRACK and SLAB_NOTRACK
Convert all allocations that used a NOTRACK flag to stop using it.
