43 * Maximum ACL we'll accept from a client; chosen (somewhat
44 * arbitrarily) so that kmalloc'ing the ACL shouldn't require a
45 * high-order allocation. This allows 204 ACEs on x86_64:
47 #define NFS4_ACL_MAX ((PAGE_SIZE - sizeof(struct nfs4_acl)) \
48 / sizeof(struct nfs4_ace))
50 int nfs4_acl_bytes(int entries);
51 int nfs4_acl_get_whotype(char *, u32);
52 __be32 nfs4_acl_write_who(struct xdr_stream *xdr, int who);
54 int nfsd4_get_nfs4_acl(struct svc_rqst *rqstp, struct dentry *dentry,
