# DF-2620 FIX VALIDATION -- variant C on the patched kernel.
# Same trigger as trigger_C.sh: same-clid MASTER+SLAVE merge (nmasters=1
# < nchains=2), umount -f, then remount + activity.
# PASS criteria: umount returns 0; no hammer2 thread left alive after
# umount (no zombies); no panic during umount or the reclaim phase.
