coda: Cache permisions in struct coda_inode_info in a kuid_t.
- Change c_uid in struct coda_indoe_info from a vuid_t to a kuid_t. - Initialize c_uid to GLOBAL_ROOT_UID instead of 0. - Use uid_eq to compare cached kuids. Cc: Jan Harkes <jaharkes@cs.cmu.edu> Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>
