User space tools usually use sscanf() to extract this field like: sscanf(buff, "%s %d", name, &num); If %-27s can break some user space tools that have assumptions about the length of the field, the orig %-17s can also break it. The longest name inotify_event_private_data is 26 bytes in 2.6.34-rc2, the tools still can't extract it.
