Also, while you're testing these: worth firing up wireshark and checking that "2"'s actually being sent in minorversion field, both on ordinary compounds and on callbacks. --b. ^ permalink raw reply [flat|nested] 23+ messages in thread

I just confirmed with these latest bits, minorversion is definitely getting set to "2". steved. ^ permalink raw reply [flat|nested] 23+ messages in thread

I didn't a config option in fs/nfsd/Kconfig for 4.1 which is the reason I didn't add one for 4.2... Should I add both? steved. ^ permalink raw reply [flat|nested] 23+ messages in thread

Should I add both? Well.... I guess if it defaults to off at runtime, and if there's a config option for labeled NFS--maybe there's no harm to it. At worst somebody turns on 4.2 by option but hey it should be fully spec-compliant as 4.2 is only optional stuff. --b. ^ permalink raw reply [flat|nested] 23+ messages in thread
