Merge tag 'nfs-for-5.1-4' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
Pull NFS client bugfixes from Trond Myklebust: "Highlights include: Stable fix: - Fix a deadlock in close() due to incorrect draining of RDMA queues Bugfixes: - Revert "SUNRPC: Micro-optimise when the task is known not to be sleeping" as it is causing stack overflows - Fix a regression where NFSv4 getacl and fs_locations stopped working - Forbid setting AF_INET6 to "struct sockaddr_in"->sin_family. - Fix xfstests failures due to incorrect copy_file_range() return values" * tag 'nfs-for-5.1-4' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: Revert "SUNRPC: Micro-optimise when the task is known not to be sleeping" NFSv4.1 fix incorrect return value in copy_file_range xprtrdma: Fix helper that drains the transport NFS: Fix handling of reply page vector NFS: Forbid setting AF_INET6 to "struct sockaddr_in"->sin_family.
