We have compiled lustre with --disable checksum as a performance
enhancement on 1.6.7.1 and would like to verify that this is actually
in affect. Reviewing /proc/fs/lustre/osc/*/checksum_type we see two
responses across all of the test system nodes
mtg[1-2],mtn1sm,mtt[1-2]
----------------
crc32 [adler]
crc32 [adler]

----------------
mtmds1
----------------
[crc32]

Is this an indication that the checksum is running? Is there a way
to verify directly that checksum is disabled or not?
