Bruce Fields Date: Mon, 9 Mar 2009 16:17:29 +0000 (-0400) Subject: nfsd4: support putpubfh operation X-Git-Tag: v2.6.30-rc1~183^2~51 X-Git-Url: http://ftp.safe.ca/?p=safe%2Fjmp%2Flinux-2.6;a=commitdiff_plain;h=a1c8c4d1ff54c6c86930ee3c4c73c69eeb9ede61;hp=31dec2538e45e9fff2007ea1f4c6bae9f78db724 nfsd4: support putpubfh operation Currently putpubfh returns NFSERR_OPNOTSUPP, which isn't actually allowed for v4. The right error is probably NFSERR_NOTSUPP. But let's just implement it; though rarely seen, it can be used by Solaris (with a special mount option), is mandated by the rfc, and is trivial for us to support. Thanks to Yang Hongyang for pointing out the original problem, and to Mike Eisler, Tom Talpey, Trond Myklebust, and Dave Noveck for further argument.... Signed-off-by: J.
