You might want to check for event_data_size here, as it's checked above.

There is no event_data_size field in a statistic snapshot event class; it's reserved in that event class. Therefore, it can't be checked in this case.

This could check stat_data_size instead, which should be the statistic snapshot equivalent. A size of 0 is allowed by the spec, so it'd be good to handle that gracefully here.

Ah, this is already being checked below before parsing and after having confirmed that it is a statistic snapshot. LGTM then.

There should probably be spaces here, something like:
| ((pevent_fifos_object != NULL)?json_create_object():NULL); | |
| pevent_fifos_object ? json_create_object() : NULL; |

Added the spaces, but decided to keep the parathesis.

This would be more consistent as __u8 reserved2[2];, but it could alternatively just be updated to the OCP 2.6 definition as __le16 nsid.

Updated it to __le16 nsid;
The Statistics Snapshot FIFO Event is in a slightly different format from the other FIFO Events. These changes account for the differences in the event formats. Signed-off-by: jeff-lien-wdc <[email protected]>

The Statistics Snapshot FIFO Event is in a slightly different format from the other FIFO Events. These changes are required for the correct parsing of the statistics snapshot event.
