From: Benjamin Coddington Date: Fri, 9 Jun 2017 15:03:23 +0000 (-0400) Subject: NFS: Fix initialization of nfs_page_array->npages X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2eb3aea7d9c43325a12df312adfc7fb25bbd636b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git NFS: Fix initialization of nfs_page_array->npages Commit 8ef9b0b9e1c0 open-coded nfs_pgarray_set(), and left out the initialization of the nfs_page_array's npages. This mistake didn't show up until testing with block layouts, and there shows that all pNFS reads return -EIO.
