v2 changes: - shorten cache names to kmalloc-rcl-<SIZE> - last patch shortens <SIZE> for all kmalloc caches to e.g. "1k", "4M" - include dma caches to the 2D kmalloc_caches[] array to avoid a branch - vmstat counter nr_indirectly_reclaimable_bytes renamed to nr_kernel_misc_reclaimable, doesn't include kmalloc-rcl-* - /proc/meminfo counter renamed to KReclaimable, includes kmalloc-rcl* and nr_kernel_misc_reclaimable Hi, as discussed at LSF/MM [1] here's a patchset that introduces kmalloc-reclaimable caches (more details in the second patch) and uses them for SLAB freelists and dcache external names. The latter allows us to repurpose the NR_INDIRECTLY_RECLAIMABLE_BYTES counter later in the series. This is how /proc/slabinfo looks like after booting in virtme: ... kmalloc-rcl-4M 0 0 4194304 1 1024 : tunables 1 1 0 : slabdata 0 0 0 ... kmalloc-rcl-96 7 32 128 32 1 : tunables 120 60 8 : slabdata 1 1 0 kmalloc-rcl-64 25 128 64 64 1 : tunables 120 60 8 : slabdata 2 2 0 kmalloc-rcl-32 0 0 32 124 1 : tunables 120 60 8 : slabdata 0 0 0 kmalloc-4M 0 0 4194304 1 1024 : tunables 1 1 0 : slabdata 0 0 0 kmalloc-2M 0 0 2097152 1 512 : tunables 1 1 0 : slabdata 0 0 0 kmalloc-1M 0 0 1048576 1 256 : tunables 1 1 0 : slabdata 0 0 0 ... /proc/vmstat with renamed nr_indirectly_reclaimable_bytes counter: ... nr_slab_reclaimable 2817 nr_slab_unreclaimable 1781 ... nr_kernel_misc_reclaimable 0 ... /proc/meminfo with new KReclaimable counter: ...
