I am on 2.6.38.8

$ grep $ /sys/block/sdk/queue/discard_*
/sys/block/sdk/queue/discard_granularity:0
/sys/block/sdk/queue/discard_max_bytes:0
/sys/block/sdk/queue/discard_zeroes_data:0

# /tmp/discard /dev/sdk5
discard: Operation not supported

Is this because of the LSI card not passing the TRIM onto the drive? Why does
hdparm report that TRIM is supported then?
