Author: mav Date: Fri Oct 2 19:41:47 2015 New Revision: 288516 URL: https://svnweb.freebsd.org/changeset/base/288516 Log: MFC r269117: Make sysctls under vfs.zfs.zfetch writeable. I don't see any reason for them to be read-only, while tuning them without reboot is much more convenient for experiments.
