Off-by-one in zap_leaf_array_create()
Trying to set user properties with their length 1 byte shorter than the maximum size triggers an assertion failure in zap_leaf_array_create(): panic[cpu0]/thread=ffffff000a092c40: assertion failed: num_integers * integer_size < (8<<10) (0x2000 < 0x2000), file: ../../common/fs/zfs/zap_leaf.c, line: 233 ffffff000a092500 genunix:process_type+167c35 () ffffff000a0925a0 zfs:zap_leaf_array_create+1d2 () ffffff000a092650 zfs:zap_entry_create+1be () ffffff000a092720 zfs:fzap_update+ed () ffffff000a0927d0 zfs:zap_update+1a5 () ffffff000a0928d0 zfs:dsl_prop_set_sync_impl+5c6 () ffffff000a092970 zfs:dsl_props_set_sync_impl+fc () ffffff000a0929b0 zfs:dsl_props_set_sync+79 () ffffff000a0929f0 zfs:dsl_sync_task_sync+10a () ffffff000a092a80 zfs:dsl_pool_sync+3a3 () ffffff000a092b50 zfs:spa_sync+4e6 () ffffff000a092c20 zfs:txg_sync_thread+297 () ffffff000a092c30 unix:thread_start+8 () This patch simply corrects the assertion.
