Commit 0cf21c66 authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'nfs-for-4.8-3' of git://git.linux-nfs.org/projects/trondmy/linux-nfs

Pull NFS client bugfixes from Trond Myklebust:
 "Highlights include:

  Stable patches:
   - Fix a refcount leak in nfs_callback_up_net
   - Fix an Oopsable condition when the flexfile pNFS driver connection
     to the DS fails
   - Fix an Oopsable condition in NFSv4.1 server callback races
   - Ensure pNFS clients stop doing I/O to the DS if their lease has
     expired, as required by the NFSv4.1 protocol

  Bugfixes:
   - Fix potential looping in the NFSv4.x migration code
   - Patch series to close callback races for OPEN, LAYOUTGET and
     LAYOUTRETURN
   - Silence WARN_ON when NFSv4.1 over RDMA is in use
   - Fix a LAYOUTCOMMIT race in the pNFS/blocks client
   - Fix pNFS timeout issues when the DS fails"
