two different users opening the same file is left to the filesystem author to
solve.
Note that there are two different types of pointers to keys that may be
encountered:
(*) struct key *
This simply points to the key structure itself. Key structures will be at
least four-byte aligned.
(*) key_ref_t
This is equivalent to a struct key *, but the least significant bit is set
if the caller "possesses" the key. By "possession" it is meant that the
calling processes has a searchable link to the key from one of its
keyrings. There are three functions for dealing with these:
key_ref_t make_key_ref(const struct key *key,
unsigned long possession);
struct key *key_ref_to_ptr(const key_ref_t key_ref);
unsigned long is_key_possessed(const key_ref_t key_ref);
The first function constructs a key reference from a key pointer and
possession information (which must be 0 or 1 and not any other value).
The second function retrieves the key pointer from a reference and the
third retrieves the possession flag.
When accessing a key's payload contents, certain precautions must be taken to
prevent access vs modification races. See the section "Notes on accessing
payload contents" for more information.
