linux-next: Tree for Jul 31

Hi all, Changes since 20180730: The block tree gained a build failure so I used the version from next-20180730. The kvms390 tree gained a conflict against the kvm-arm tree. The staging tree still had its build failure due to an interaction with the vfs tree for which I disabled CONFIG_EROFS_FS.

We can use the newly introduced kmalloc-reclaimable-X caches, to allocate external names in dcache, which will take care of the proper accounting automatically, and also improve anti-fragmentation page grouping. This effectively reverts commit f1782c9bc547 ("dcache: account external names as indir

[PATCH v4 1/6] mm, slab: combine kmalloc_caches and kmalloc_dma_caches

The kmalloc caches currently mainain separate (optional) array kmalloc_dma_caches for __GFP_DMA allocations. There are tests for __GFP_DMA in the allocation hotpaths. We can avoid the branches by combining kmalloc_caches and kmalloc_dma_caches into a single two-dimensional array where the outer dim

[PATCH v4 4/6] mm: rename and change semantics of nr_indirectly_reclaimable_bytes

The vmstat counter NR_INDIRECTLY_RECLAIMABLE_BYTES was introduced by commit eb59254608bc ("mm: introduce NR_INDIRECTLY_RECLAIMABLE_BYTES") with the goal of accounting objects that can be reclaimed, but cannot be allocated via a SLAB_RECLAIM_ACCOUNT cache. This is now possible via kmalloc() with __G

[PATCH v4 5/6] mm, proc: add KReclaimable to /proc/meminfo

The vmstat NR_KERNEL_MISC_RECLAIMABLE counter is for kernel non-slab allocations that can be reclaimed via shrinker. In /proc/meminfo, we can show the sum of all reclaimable kernel allocations (including slab) as "KReclaimable". Add the same counter also to per-node meminfo under /sys With this co

[PATCH v4 6/6] mm, slab: shorten kmalloc cache names for large sizes

Kmalloc cache names can get quite long for large object sizes, when the sizes are expressed in bytes. Use 'k' and 'M' prefixes to make the names as short as possible e.g. in /proc/slabinfo. This works, as we mostly use power-of-two sizes, with exceptions only below 1k. Example: 'kmalloc-4194304' b

[PATCH v4 2/6] mm, slab/slub: introduce kmalloc-reclaimable caches

Kmem caches can be created with a SLAB_RECLAIM_ACCOUNT flag, which indicates they contain objects which can be reclaimed under memory pressure (typically through a shrinker). This makes the slab pages accounted as NR_SLAB_RECLAIMABLE in vmstat, which is reflected also the MemAvailable meminfo count

v4 changes: - drop mm, slab: allocate off-slab freelists as reclaimable when appropriate - per Mel, reclaiming objects from a slab doesn't guarantee that the whole slab page will be freed and freelist reclaimed, so it can do more harm than good - change KMALLOC_* constants from #define to
