Christian Schwarz e439ee83c1 linux: zvol: avoid heap allocation for zvol_request_sync=1 ... The spl_kmem_alloc showed up in some flamegraphs in a single-threaded 4k sync write workload at 85k IOPS on an Intel(R) Xeon(R) Silver 4215 CPU @ 2.50GHz. Certainly not a huge win but I believe the change is clean and easy to maintain down the road.
