Manual trims fall into the category of long-running pool activities which people might want to wait synchronously for. This change adds support to 'zpool wait' for waiting for manual trim operations to complete. It also adds a '-w' flag to 'zpool trim' which can be used to turn 'zpool trim' into a synchronous operation.

# DESCRIPTION:
|
|
# Check various pool geometries stripe, mirror, raidz
|
|
#
|
|
# STRATEGY:
|
|
# 1. Create a pool on file vdevs to trim.
|
|
# 2. Fill the pool to a known percentage of capacity.
|
|
# 3. Verify the vdevs contain 75% or more allocated blocks.
|
|
# 4. Remove all files making it possible to trim the entire pool.
|
|
# 5. Manually trim the pool.
|
|
# 6. Wait for trim to issue trim IOs for the free blocks.
|
|
# 7. Verify the disks contain 30% or less allocated blocks.
|
|
# 8. Repeat for test for striped, mirrored, and RAIDZ pools.
