Subject: [PATCH 0/2] mm: two allocator fixes for 6.15
Date: Wed, 16 Apr 2025 09:45:38 -0400 [thread overview]
Message-ID: <20250416135142.778933-1-hannes@cmpxchg.org> (raw)
Two fixes based on Vlastimil's review of the defrag_mode patches.
#1 fixes a bug that can lead to memory deadlocks on high-CPU-count
machines. This affects not just defrag_mode.
#2 fixes an overreclaim issue when defrag_mode is enabled.
Based on:
commit 16176182efbf3dfce6dad18dcc8801164329d1c2 (akpm/mm-hotfixes-unstable)
