- Default SPL_KMEM_CACHE_DELAY changed to 15 to match Solaris. - Aged out slab checking occurs every SPL_KMEM_CACHE_DELAY / 3. - skc->skc_reap tunable added whichs allows callers of spl_slab_reclaim() to cap the number of slabs reclaimed. On Solaris all eligible slabs are always reclaimed, and this is still the default behavior. However, I suspect that is not always wise for reasons such as in the next comment. - spl_slab_reclaim() added cond_resched() while walking the slab/object free lists. Soft lockups were observed when freeing large numbers of vmalloc'd slabs/objets. - spl_slab_reclaim() 'sks->sks_ref > 0' check changes from incorrect 'break' to 'continue' to ensure all slabs are checked. - spl_cache_age() reworked to avoid a deadlock with do_flush_tlb_all() which occured because we slept waiting for completion in spl_cache_age(). To waiting for magazine reclamation to finish is not required so we no longer wait. - spl_magazine_create() and spl_magazine_destroy() shifted back to using for_each_online_cpu() instead of the spl_on_each_cpu() approach which was of course a bad idea due to memory allocations which Ricardo pointed out. |
