The Linux slab, in general, performs better than the SPl slab in cases where a lot of objects are allocated and fragmentation is likely present. This patch fixes pathologically bad behavior in cases where the ARC is filled with mostly metadata and a user program needs to allocate and dirty enough memory which would require an insignificant amount of the ARC to be reclaimed. If zfs_znode_cache is on the SPL slab, the system may spin for a very long time trying to reclaim sufficient memory. If it is on the Linux slab, the behavior has been observed to be much more predictible; the memory is reclaimed more efficiently.
