I already have a patch for this in the tiny tree (tiny/no-rhashtable), using a non-user-visible Kconfig symbol. Sorry that you ran into some projects that have already been completed. I'll try to keep the tinification projects list more up to date; I've been getting patches *very* rapidly, and just about the entire "small" project list is either done or in progress. - Josh Triplett > lib/Kconfig | 6 ++++++ > lib/Makefile | 4 +++- > net/Kconfig | 1 + > 3 files changed, 10 insertions(+), 1 deletion(-) > > diff --git a/lib/Kconfig b/lib/Kconfig > index 108196c..d6b8879 100644 > --- a/lib/Kconfig > +++ b/lib/Kconfig > @@ -369,6 +369,12 @@ config ASSOCIATIVE_ARRAY > > for more information. > > +config RHASH_TABLE > + bool "Resizable hash table" > + default y > + help > + Resizable, scalable and concurrent hash table implementation. > + > config HAS_IOMEM > boolean > depends on !NO_IOMEM > diff --git a/lib/Makefile b/lib/Makefile > index 53fd120..43d29ff 100644 > --- a/lib/Makefile > +++ b/lib/Makefile > @@ -26,7 +26,7 @@ obj-y += bcd.o div64.o sort.o parser.o debug_locks.o > random32.o \ > bust_spinlocks.o hexdump.o kasprintf.o bitmap.o scatterlist.o \ > gcd.o lcm.o list_sort.o uuid.o iovec.o clz_ctz.o \ > bsearch.o find_last_bit.o find_next_bit.o llist.o memweight.o kfifo.o \ > - percpu-refcount.o percpu_ida.o hash.o rhashtable.o > + percpu-refcount.o percpu_ida.o hash.o > obj-y += string_helpers.o > obj-$(CONFIG_TEST_STRING_HELPERS) += test-string_helpers.o > obj-y += kstrtox.o > @@ -155,6 +155,8 @@ obj-$(CONFIG_GENERIC_NET_UTILS) += net_utils.o > > obj-$(CONFIG_STMP_DEVICE) += stmp_device.o > > +obj-$(CONFIG_RHASH_TABLE) += rhashtable.o > + > libfdt_files = fdt.o fdt_ro.o fdt_wip.o fdt_rw.o fdt_sw.o fdt_strerror.o \ > fdt_empty_tree.o > $(foreach file, $(libfdt_files), \ > diff --git a/net/Kconfig b/net/Kconfig > index 99815b5..d376630 100644 > --- a/net/Kconfig > +++ b/net/Kconfig > @@ -7,6 +7,7 @@ menuconfig NET > select NLATTR > select GENERIC_NET_UTILS > select BPF > + select RHASH_TABLE > ---help--- > Unless you really know what you are doing, you should say Y here. > The reason is that some programs need kernel networking support even > -- > 1.8.3.1 > -- 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/
