Important: And then *remove* the "select SCSI_ESP_CORE" from the Kconfig options of the front-ends themselves. [ You could do something similar with SCSI_SPI_ATTRS also, it looks like to be something that probably never makes sense alone either, and needs only to be automatically pulled in by other options (?) ] [ Note that "select"ing stuff that is not library-like and itself depends on other stuff is a Bad Thing. ] > but on the otherhand I like how anyone can select it and thus > test the build of it :-) Satyam - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
