Browse Source 
in linux below patches remove the support for QUEUE_FLAG_DISCARD
and QUEUE_FLAG_SECERASE.

    block: remove QUEUE_FLAG_DISCARD

    Just use a non-zero max_discard_sectors as an indicator for discard
    support, similar to what is done for write zeroes.

    The only places where needs special attention is the RAID5 driver,
    which must clear discard support for security reasons by default,
    even if the default stacking rules would allow for it.

    block: decouple REQ_OP_SECURE_ERASE from REQ_OP_DISCARD

    Secure erase is a very different operation from discard in that it is
    a data integrity operation vs hint.  Fully split the limits and helper
    infrastructure to make the separation more clear.

we are fixing below compilation error using this patch.
