Subject: [PATCH v1 0/2] mm: move pte table reclaim code to memory.c
Date: Mon, 19 Jan 2026 23:07:06 +0100 [thread overview]
Message-ID: <20260119220708.3438514-1-david@kernel.org> (raw)
Some cleanups for PT table reclaim code, triggered by a false-positive
warning we might start to see soon after we unlocked pt-reclaim on
architectures besides x86-64.
Cross compiled on plenty of architectures, tested on x86-64 with
a simple test case that allocates plenty of page tables in a sparse
memory area to see if they will get reclaimed.
