From 519129ff4e717f3026ae70b58d2db59d937aef06 Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Wed, 20 Jan 2016 15:58:29 -0800 Subject: Illumos 6815179, 6844191 6815179 zpool import with a large number of LUNs is too slow 6844191 zpool import, scanning of disks should be multi-threaded References: https://github.com/illumos/illumos-gate/commit/4f67d75 Porting notes: - This change was originally never ported to Linux due to it dependence on the thread pool interface. This patch solves that issue by switching the code to use the existing taskq implementation which provides the same basic functionality. However, in order for this to work properly thread_init() and thread_fini() must be called around to taskq consumer to perform the needed thread initialization. - The check_one_slice, nozpool_all_slices, and check_slices functions have been disabled for Linux. They are difficult, but possible, to implement for Linux due to how partitions are get names. Since this is only an optimization this code can be added at a latter date.
