  nfs4: resend LAYOUTGET when there is a race that changes the seqid (2015-11-25 15:32:13 -0500)

----------------------------------------------------------------
NFS client bugfixes for Linux 4.4

Highlights include:

Stable patches:
- Fix a NFSv4 callback identifier leak that was also causing client crashes
- Fix NFSv4 callback decoding issues when incoming requests are truncated
- Don't declare the attribute cache valid when we call nfs_update_inode with
  an empty attribute structure.
- Resend LAYOUTGET when there is a race that changes the seqid

Bugfixes:
- Fix a number of issues with the NFSv4.2 CLONE ioctl()
- Properly set NFS v4.2 NFSDBG_FACILITY
- NFSv4 referrals are broken; Cleanup FATTR4_WORD0_FS_LOCATIONS after
  decoding success
- Use sliding delay when LAYOUTGET gets NFS4ERR_DELAY
- Ensure that attrcache is revalidated after a SETATTR

----------------------------------------------------------------
