30 * Command to output io and checksum ereport values, one per line.
31 * Used by zpool_events_duplicates.ksh to check for duplicate events.
33 * example output line:
35 * checksum "error_pool" 0x856dd01ce52e336 0x000034 0x000400 0x000a402c00
36 * 0x000004 0x000000 0x000000 0x000000 0x000001
40 * Our ereport duplicate criteria
42 * When the class and all of these values match, then an ereport is
43 * considered to be a duplicate.
