ceph: Translate between uid and gids in cap messages and kuids and kgids
- Make the uid and gid arguments of send_cap_msg() used to compose
ceph_mds_caps messages of type kuid_t and kgid_t.
- Pass inode->i_uid and inode->i_gid in __send_cap to send_cap_msg()
through variables of type kuid_t and kgid_t.
- Modify struct ceph_cap_snap to store uids and gids in types kuid_t
and kgid_t. This allows capturing inode->i_uid and inode->i_gid in
ceph_queue_cap_snap() without loss and pssing them to
__ceph_flush_snaps() where they are removed from struct
ceph_cap_snap and passed to send_cap_msg().
- In handle_cap_grant translate uid and gids in the initial user
namespace stored in struct ceph_mds_cap into kuids and kgids
before setting inode->i_uid and inode->i_gid.
