Parallel pool import
This commit allow spa_load() to drop the spa_namespace_lock so that imports can happen concurrently. Prior to dropping the spa_namespace_lock, the import logic will set the spa_load_thread value to track the thread which is doing the import. Consumers of spa_lookup() retain the same behavior by blocking when either a thread is holding the spa_namespace_lock or the spa_load_thread value is set. This will ensure that critical concurrent operations cannot take place while a pool is being imported. The zpool command is also enhanced to provide multi-threaded support when invoking zpool import -a. Lastly, zinject provides a mechanism to insert artificial delays when importing a pool and new zfs tests are added to verify parallel import functionality.

# DESCRIPTION:
|
||||
# Verify that pool imports can occur in parallel
|
||||
#
|
||||
# STRATEGY:
|
||||
# 1. Create 8 pools
|
||||
# 2. Generate some ZIL records
|
||||
# 3. Export the pools
|
||||
# 4. Import half of the pools synchronously to baseline sequential cost
|
||||
# 5. Import the other half asynchronously to demonstrate parallel savings
|
||||
# 6. Export 4 pools
|
||||
# 7. Test zpool import -a

||||
