If you mean the in-kernel nfsd (CONFIG_NFSD), that already has a large stack of "select" and "depends on", both directly and indirectly; adding a "select SPLICE_SYSCALL" to it seems fine. (That select does need adding, though. Pieter, you need to test-compile more than just tinyconfig and defconfig. Try an allyesconfig with *just* splice turned off, and make sure that compiles.) Given the requirements of running a file server in the kernel, I'd expect CONFIG_NFSD to end up with several more selects of optional functionality in the future. It seems rather likely that the average embedded system will be compiling out NFS. :) Also, this patch series compiles out splice and sendfile, including several *users* of sendpage; it doesn't compile out the sendpage support/infrastructure itself. - Josh Triplett -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
