From bfdd89f232aa2de5a4b3fc985cba894148b830a8 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Wed, 24 Feb 2021 13:39:50 -0500 Subject: [PATCH] nfsd: don't abort copies early The typical result of the backwards comparison here is that the source server in a server-to-server copy will return BAD_STATEID within a few seconds of the copy starting, instead of giving the copy a full lease period, so the copy_file_range() call will end up unnecessarily returning a short read.
