[PATCH 04/14] rcutorture: Make torture.sh --do-rt use CONFIG_PREEMPT_RT

by Joel Fernandes

From: "Paul E. McKenney" <paulmck(a)kernel.org> The torture.sh --do-rt command-line parameter is intended to mimic -rt kernels. Now that CONFIG_PREEMPT_RT is upstream, this commit makes this mimicking more precise. Note that testing of RCU priority boosting is disabled in favor of forward-progress testing of RCU callbacks. If it turns out to be possible to make kernels built with CONFIG_PREEMPT_RT=y to tolerate testing of both, both will be enabled. [ paulmck: Apply Sebastian Siewior feedback. ] Signed-off-by: Paul E.

[PATCH v6 05/18] rust: kunit: refactor to use `&raw [const|mut]`

by Antonio Hickey

Replacing all occurrences of `addr_of!(place)` and `addr_of_mut!(place)` with `&raw const place` and `&raw mut place` respectively. This will allow us to reduce macro complexity, and improve consistency with existing reference syntax as `&raw const`, `&raw mut` are similar to `&`, `&mut` making it fit more naturally with other existing code.

[PATCH v4 0/4] mm: introduce THP deferred setting

by Nico Pache

This series is a follow-up to [1], which adds mTHP support to khugepaged. mTHP khugepaged support is a "loose" dependency for the sysfs/sysctl configs to make sense. Without it global="defer" and mTHP="inherit" case is "undefined" behavior. We've seen cases were customers switching from RHEL7 to RHEL8 see a significant increase in the memory footprint for the same workloads. Through our investigations we found that a large contributing factor to the increase in RSS was an increase in THP usage. For workloads like MySQL, or when using allocators like jemalloc, it is often recommended to set /transparent_hugepages/enabled=never. This is in part due to performance degradations and increased memory waste. This series introduces enabled=defer, this setting acts as a middle ground between always and madvise. If the mapping is MADV_HUGEPAGE, the page fault handler will act normally, making a hugepage if possible. If the allocation is not MADV_HUGEPAGE, then the page fault handler will default to the base size allocation. The caveat is that khugepaged can still operate on pages thats not MADV_HUGEPAGE. This allows for three things... one, applications specifically designed to use hugepages will get them, and two, applications that don't use hugepages can still benefit from them without aggressively inserting THPs at every possible chance. This curbs the memory waste, and defers the use of hugepages to khugepaged. Khugepaged can then scan the memory for eligible collapsing. Lastly there is the added benefit for those who want THPs but experience higher latency PFs. Now you can get base page performance at the PF handler and Hugepage performance for those mappings after they collapse. Admins may want to lower max_ptes_none, if not, khugepaged may aggressively collapse single allocations into hugepages. TESTING: - Built for x86_64, aarch64, ppc64le, and s390x - selftests mm - In [1] I provided a script [2] that has multiple access patterns - lots of general use. - redis testing. This test was my original case for the defer mode. What I was able to prove was that THP=always leads to increased max_latency cases; hence why it is recommended to disable THPs for redis servers. However with 'defer' we dont have the max_latency spikes and can still get the system to utilize THPs. I further tested this with the mTHP defer setting and found that redis (and probably other jmalloc users) can utilize THPs via defer (+mTHP defer) without a large latency penalty and some potential gains. I uploaded some mmtest results here[3] which compares: stock+thp=never stock+(m)thp=always khugepaged-mthp + defer (max_ptes_none=64) The results show that (m)THPs can cause some throughput regression in some cases, but also has gains in other cases. The mTHP+defer results have more gains and less losses over the (m)THP=always case.

[PATCH net-next v2 0/4] Fix netdevim to correctly mark NAPI IDs

Greetings: Welcome to v2. This series fixes netdevsim to correctly set the NAPI ID on the skb. This is helpful for writing tests around features that use SO_INCOMING_NAPI_ID. In addition to the netdevsim fix in patch 1, patches 2-4 do some self test refactoring and add a test for NAPI IDs. The test itself (patch 4) introduces a C helper because apparently python doesn't have socket.SO_INCOMING_NAPI_ID.
