Other kernel developers and kernel testers are particularly valuable kernel users (by which I mean, valuable to us, since they do useful work for us) who often use new kernels on old distributions. > In addition, rpcbind/libtirpc are still not entirely stable (API/ABI- > wise) so it may be better to leave this as a hard compile-time switch > until distributions are comfortable replacing portmap with rpcbind. Making it easy to switch between portmap and (newer) rpcbind daemons might make it easier to test and debug the newer code. None of this is in contradiction to what you've said--it's a tradeoff--but on balance I'd prefer the additional svc_register() logic. --b. > >> --b. >> >>> CONFIG_RPCSEC_GSS_KRB5=m >>> # CONFIG_RPCSEC_GSS_SPKM3 is not set >>> >>> ===== * ===== * ===== * ===== >>> >>> # rpcinfo -p localhost >>> program vers proto port >>> 100000 2 tcp 111 portmapper >>> 100000 2 udp 111 portmapper >>> 100024 1 udp 34971 status >>> 100024 1 tcp 43460 status >>> 100005 1 udp 34365 mountd >>> 100005 1 tcp 44349 mountd >>> 100005 2 udp 34365 mountd >>> 100005 2 tcp 44349 mountd >>> 100005 3 udp 34365 mountd >>> 100005 3 tcp 44349 mountd >>> >>> ===== * ===== * ===== * ===== >>> >>> lsmod >>> >>> Module Size Used by >>> nfs 206772 0 >>> nfsd 185008 9 >>> lockd 55160 2 nfs,nfsd >>> nfs_acl 2688 2 nfs,nfsd >>> auth_rpcgss 28548 1 nfsd >>> sunrpc 144584 9 nfs,nfsd,lockd,nfs_acl,auth_rpcgss >>> exportfs 3456 1 nfsd >>> fuse 42268 0 >>> usbhid 13588 0 >>> usbmouse 3712 0 >>> usbkbd 4992 0 >>> floppy 45348 0 >>> pcspkr 2176 0 >>> i2c_i801 7952 0 >>> r8169 26500 0 >>> i2c_core 17680 1 i2c_i801 >>> mii 4224 1 r8169 >>> snd_intel8x0 25500 0 >>> snd_ac97_codec 88352 1 snd_intel8x0 >>> ehci_hcd 28684 0 >>> uhci_hcd 18444 0 >>> ac97_bus 1536 1 snd_ac97_codec >>> snd_pcm 48008 2 snd_intel8x0,snd_ac97_codec >>> snd_timer 15364 1 snd_pcm >>> snd 34788 4 >>> snd_intel8x0,snd_ac97_codec,snd_pcm,snd_timer >>> usbcore 104760 6 >>> usbhid,usbmouse,usbkbd,ehci_hcd,uhci_hcd >>> snd_page_alloc 7304 2 snd_intel8x0,snd_pcm >>> intel_agp 22588 1 >>> agpgart 25520 1 intel_agp >>> button 5904 0 >>> >>> -- >>> To unsubscribe from this list: send the line "unsubscribe linux-nfs" >>> in >>> the body of a message to majordomo@xxxxxxxxxxxxxxx >>> More majordomo info at http://vger.kernel.org/majordomo-info.html > > -- > Chuck Lever > chuck[dot]lever[at]oracle[dot]com > > > -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
