Merge tag 'nfsd-6.3-5' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux
Pull nfsd fixes from Chuck Lever:
- Fix a crash and a resource leak in NFSv4 COMPOUND processing
- Fix issues with AUTH_SYS credential handling
- Try again to address an NFS/NFSD/SUNRPC build dependency regression
* tag 'nfsd-6.3-5' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux:
NFSD: callback request does not use correct credential for AUTH_SYS
NFS: Remove "select RPCSEC_GSS_KRB5
sunrpc: only free unix grouplist after RCU settles
nfsd: call op_release, even when op_func returns an error
NFSD: Avoid calling OPDESC() with ops->opnum == OP_ILLEGAL
