No, because if the disk is RPM_SUSPENDED, the port may be RPM_SUSPENDED, which likely means that you CAN'T send down requests to the device. We need to put the device into one of the transitioning states to block other IO, without allowing the port to suspend. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJSzsXvAAoJEI5FoCIzSKrwg30H/A52cy6+GAzE372KVMkP/bI+ LQe4FTTIjo8PDBuYeASzmjdiD8x51++w/QfUQEtSTEhr7qWhyXdMbb1B6eGuDlv/ KqOBTTuhC7eiLArGLTGyLRiLOLEiQb7lHStw4ZCpQpZ88f9pNPdcLCslp8zrz4Of 6pt2lLztdG8zexmKyu0Zq/oSe6ajKqVgrSqjoCO9jQL7NUecZNlBnOnsF4jri0MY GPk3HIb0gZjtVVfeWAiEE9s4MpRlMYHfx+dg8uxNJiAhJcMQeHJLCTKAKyEMKG68 45Ehqp5XITJG8Mx/Mb6gOzA/mFDShzqRiA0i6MtKBcnr+zNeRnWKRV1UbDKcrxk= =B5lj -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
