Illumos 5176 - lock contention on godfather zio
5176 lock contention on godfather zio Reviewed by: Adam Leventhal <[email protected]> Reviewed by: Alex Reece <[email protected]> Reviewed by: Christopher Siden <[email protected]> Reviewed by: George Wilson <[email protected]> Reviewed by: Richard Elling <[email protected]> Reviewed by: Bayard Bell <[email protected]> Approved by: Garrett D'Amore <[email protected]> References: https://www.illumos.org/issues/5176 https://github.com/illumos/illumos-gate/commit/6f834bc Porting notes: Under Linux max_ncpus is defined as num_possible_cpus(). This is largest number of cpu ids which might be available during the life time of the system boot. This value can be larger than the number of present cpus if CONFIG_HOTPLUG_CPU is defined. Ported by: Turbo Fredriksson <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #2711
