From 99c72652f81ca5ea212adbb5a555e12a4de94491 Mon Sep 17 00:00:00 2001 From: Jiffin Tony Thottan Date: Thu, 29 Nov 2018 19:22:40 +0530 Subject: nfs : set ctx for every inode looked up nfs3_fh_resolve_inode_lookup_cbk() The inode ctx for nfs xlator is set with help nfs_fix_generation. But currently gnfs is crashing because inode_ctx is becoming null nfs3_resolve_inode_hard() is used to perform a lookup on entire path and looks like function is missing to set the ctx for inode. This patch will set ctx for the inode which it looked on.
