60 structure maintains per uid resource consumption counts, including the
61 process count and socket buffer space usage.
65 function initializes the
67 hash table and its mutex.
68 This function should only be called during system initialization.
72 function looks up and returns the
80 a new structure will be allocated and initialized.
83 hash mutex is acquired and released.
87 function increases the reference count on
90 lock is acquired and released.
94 function decreases the reference count on
96 and if the count reaches 0
100 lock is acquired and release and the uidinfo hash mutex may be
101 acquired and released.
104 returns a pointer to an initialized
106 structure, and should not fail.
