Hello Greg,
Can you please consider including the following patches in the stable linux-4.14.y branch?
The following patch series attempts to address the issues raised by Stan Hu around NFSv4 lookup revalidation.
The first patch in the series should, in principle suffice to address the exact issue raised by Stan, however when looking at the implementation of nfs4_lookup_revalidate(), it becomes clear that we're not doing enough to revalidate the dentry itself when performing NFSv4.1 opens either.
You can not just ignore the 4.19.y kernel tree for these patches, as when you all finally move forward from 4.14.y to 4.19.y, you would have hit these same exact issues :(
I have also queued them up to 4.19.y.
Well, except for the last patch, that's not needed at all.
thanks,
