Tony Nguyen c8bbf7c00b Improve write performance by using dmu_read_by_dnode() ... In zfs_log_write(), we can use dmu_read_by_dnode() rather than dmu_read() thus avoiding unnecessary dnode_hold() calls. We get a 2-5% performance gain for large sequential_writes tests, >=128K writes to files with recordsize=8K. Testing done on Ubuntu 18.04 with 4.15 kernel, 8vCPUs and SSD storage on VMware ESX.
