Here's the command line used for testing: iozone -az -n 4k -g 2048m -y 1k -q 1m -e I also ran fs_mark using the following command line: fs_mark -S 1 -D 100 -N 1000 -d /mnt/test/fs_mark -s 65536 -t 1 -w 4096 I'll let you know if there are any regressions caused by this patch in any of our other testing.
