This patch adds support for multiple security options which can be specified using a colon-delimited list of security flavors (the same syntax as nfsd's exports file). This is useful, for instance, when NFSv4.x mounts cross SECINFO boundaries. With this patch a user can use "sec=krb5i,krb5p" to mount a remote filesystem using krb5i, but can still cross into krb5p-only exports. New mounts will try all security options before failing. NFSv4.x SECINFO results will be compared against the sec= flavors to find the first flavor in both lists or if no match is found will return -EPERM. Signed-off-by:
