[LTP] [PATCH v3 1/6] ima/ima_boot_aggregate: Fix the definition of event log

[Jia Zhang]

According to [1], the structure of event log should be packed,
and certain fields should be 32-bit unsigned integer. Fortunately,
keeping natural alignment seems to make everything working as
expected all the time.
