Merge tag 'nfs-for-4.10-2' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
Pull more NFS client updates from Trond Myklebust: "Highlights include: - further attribute cache improvements to make revalidation more fine grained - NFSv4 locking improvements Bugfixes: - nfs4_fl_prepare_ds must be careful about reporting success in files layout - pNFS/flexfiles: Instead of marking a device inactive, remove it from the cache" * tag 'nfs-for-4.10-2' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: NFSv4: Retry the DELEGRETURN if the embedded GETATTR is rejected with EACCES NFS: Retry the CLOSE if the embedded GETATTR is rejected with EACCES NFSv4: Place the GETATTR operation before the CLOSE NFSv4: Also ask for attributes when downgrading to a READ-only state NFS: Don't abuse NFS_INO_REVAL_FORCED in nfs_post_op_update_inode_locked() pNFS: Return RW layouts on OPEN_DOWNGRADE NFSv4: Add encode/decode of the layoutreturn op in OPEN_DOWNGRADE NFS: Don't disconnect open-owner on NFS4ERR_BAD_SEQID NFSv4: ensure __nfs4_find_lock_state returns consistent result. NFSv4.1: nfs4_fl_prepare_ds must be careful about reporting success. pNFS/flexfiles: delete deviceid, don't mark inactive NFS: Clean up nfs_attribute_timeout() NFS: Remove unused function nfs_revalidate_inode_rcu() NFS: Fix and clean up the access cache validity checking NFS: Only look at the change attribute cache state in nfs_weak_revalidate() NFS: Clean up cache validity checking NFS: Don't revalidate the file on close if we hold a delegation NFSv4: Don't discard the attributes returned by asynchronous DELEGRETURN NFSv4: Update the attribute cache info in update_changeattr
