Author: allanjude Date: Tue May 21 21:26:18 2019 New Revision: 348068 URL: https://svnweb.freebsd.org/changeset/base/348068 Log: ZFS: Make deadman tunables no longer read-only This allows the user to enable, disable, and adjust the I/O deadman at runtime. This can be especially useful when a pool is backed by remote storage (such as iscsi, ggated, etc).
