    Subject[PATCH 4.6 89/96] libata: LITE-ON CX1-JB256-HP needs lower max_sectors
    Date
    4.6-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Tejun Heo <tj@kernel.org>

    commit 1488a1e3828d60d74c9b802a05e24c0487babe4e upstream.

    Since 34b48db66e08 ("block: remove artifical max_hw_sectors cap"),
    max_sectors is no longer limited to BLK_DEF_MAX_SECTORS and LITE-ON
    CX1-JB256-HP keeps timing out with higher max_sectors. Revert it to
    the previous value.
