Subject: [PATCH] NFS: Fix initialization of nfs_page_array->npages
Date: Fri, 9 Jun 2017 11:03:23 -0400 [thread overview]
Message-ID: <a0aadd8ba44801d294fb919412c85f6b39bea852.1497020554.git.bcodding@redhat.com> (raw)
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.
Fixes: 8ef9b0b9e1c0 ("NFS: move nfs_pgarray_set() to open code")
