Merge tag 'nfs-for-4.13-5' of git://git.linux-nfs.org/projects/anna/linux-nfs
Pull NFS client fixes from Anna Schumaker:
"A few more NFS client bugfixes from me for rc5.
Dros has a stable fix for flexfiles to prevent leaking the
nfs4_ff_ds_version arrays when freeing a layout, Trond fixed a
potential recovery loop situation with the TEST_STATEID operation, and
Christoph fixed up the pNFS blocklayout Kconfig options to prevent
unsafe use with kernels that don't have large block device support.
Summary:
Stable fix:
- fix leaking nfs4_ff_ds_version array
Other fixes:
- improve TEST_STATEID OLD_STATEID handling to prevent recovery loop
- require 64-bit sector_t for pNFS blocklayout to prevent 32-bit
compile errors"
