commit 3bcaad5930046d64645923dd2286dff3dce09eed Author: Rick Macklem <[email protected]> AuthorDate: 2021-04-27 00:48:21 +0000 Commit: Rick Macklem <[email protected]> CommitDate: 2021-05-11 01:14:20 +0000 nfscl: fix the handling of NFSERR_DELAY for Open/LayoutGet RPCs For a pNFS mount, the NFSv4.1/4.2 client uses compound RPCs that have both Open and LayoutGet operations in them. If the pNFS server were tp reply NFSERR_DELAY for one of these compounds, the retry after a delay cannot be handled by newnfs_request(), since there is a reference held on the open state for the Open operation in them. Fix this by adding these RPCs to the "don't do delay here" list in newnfs_request(). This patch is only needed if the mount is using pNFS (the "pnfs" mount option) and probably only matters if the MDS server is issuing delegations as well as pNFS layouts. Found by code inspection.
