Merge tag 'nfs-for-3.12-2' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
Pull NFS client bugfixes (part 2) from Trond Myklebust: "Bugfixes: - Fix a few credential reference leaks resulting from the SP4_MACH_CRED NFSv4.1 state protection code. - Fix the SUNRPC bloatometer footprint: convert a 256K hashtable into the intended 64 byte structure. - Fix a long standing XDR issue with FREE_STATEID - Fix a potential WARN_ON spamming issue - Fix a missing dprintk() kuid conversion New features: - Enable the NFSv4.1 state protection support for the WRITE and COMMIT operations" * tag 'nfs-for-3.12-2' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: SUNRPC: No, I did not intend to create a 256KiB hashtable sunrpc: Add missing kuids conversion for printing NFSv4.1: sp4_mach_cred: WARN_ON -> WARN_ON_ONCE NFSv4.1: sp4_mach_cred: no need to ref count creds NFSv4.1: fix SECINFO* use of put_rpccred NFSv4.1: sp4_mach_cred: ask for WRITE and COMMIT NFSv4.1 fix decode_free_stateid
