Steve (see https://lkml.org/lkml/2014/3/11/218 ) and James,

Are the labels on data output in LSM_AUDIT_DATA_TASK even right?  The
general case gives pid and comm of current.  Then the
LSM_AUDIT_DATA_TASK case gives pid and comm from the task handed in in
the struct common_audit_data pointer.  They are a duplicate of the
general case without generating a new message.  I expect this will cause
ausearch to ignore those latter two fields.  Should the latter two be
renamed to something like ad_pid= and ad_comm= ?

Tetsuo, this conversation should have been on the linux-audit@xxxxxxxxxx
list the whole time...
