Subject: [PATCH] NFS: Fix initialisation of I/O result struct in
nfs_pgio_rpcsetup
Git-commit: 17d8c5d145000070c581f2a8aa01edc7998582ab
Patch-mainline: v5.3
References: git-fixes
Initialise the result count to 0 rather than initialising it to the
argument count. The reason is that we want to ensure we record the
I/O stats correctly in the case where an error is returned (for
instance in the layoutstats).
