    sata_sil: disable trim · d98f1cd0
    Mikulas Patocka authored
    When I connect an Intel SSD to SATA SIL controller (PCI ID 1095:3114), any
    TRIM command results in I/O errors being reported in the log. There is
    other similar error reported with TRIM and the SIL controller:
    https://bugs.centos.org/view.php?id=5880
    
    Apparently the controller doesn't support TRIM commands. This patch
    disables TRIM support on the SATA SIL controller.
