From: Jeff Layton Date: Thu, 20 Oct 2016 16:21:34 +0000 (-0400) Subject: nfsd: fix error handling for clients that fail to return the layout X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=851238a22f3be7323feed6a62a6882c284b2f0a5;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git nfsd: fix error handling for clients that fail to return the layout Currently, when the client continually returns NFS4ERR_DELAY on a CB_LAYOUTRECALL, we'll give up trying to retransmit after two lease periods, but leave the layout in place. What we really need to do here is fence the client in this case. Have it fall through to that code in that case instead of into the NFS4ERR_NOMATCHING_LAYOUT case.
