Subject: [patch 0/6] mm/vmalloc: Assorted fixes and improvements
Date: Tue, 23 May 2023 16:02:09 +0200 (CEST) [thread overview]
Message-ID: <20230523135902.517032811@linutronix.de> (raw)
Following up to the discussion about excessive TLB flushes
https://lore.kernel.org/all/87a5y5a6kj.ffs@tglx
this series addresses the following issues:
1) Prevent the stale TLB problem related to fully utilized vmap blocks
2) Avoid the double per CPU list walk in _vm_unmap_aliases()
3) Avoid flushing dirty space over and over
4) Add a lockless quickcheck in vb_alloc() and add missing
READ/WRITE_ONCE() annotations
5) Prevent overeager purging of usable vmap_blocks if
not under memory/address space pressure.
Thanks,
tglx
