Replace GNU-specific du flags (--block-size, -B1) and dd conv=nocreat with POSIX compatible commands. Move -O flag before pool name in zpool create to align with FreeBSD's strict POSIX getopt(). Relax vdev size thresholds in trim_config to account for ZFS-on-ZFS overhead. Add sync_pool before zpool trim -w to ensure freed blocks are committed before trimming. Skip zpool_trim_partial, zpool_trim_verify_trimmed, trim_config, and autotrim_config on FreeBSD where trim does not reclaim space on file vdevs stored on a ZFS filesystem within the test framework. Tested on FreeBSD 16.0-CURRENT: 26 PASS, 4 SKIP, 0 FAIL. Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Christos Longros <[email protected]> Closes #18398
