rhashtable_shrink

Name:hashtable_shrink - Shrink hash table while allowing concurrent lookups*@ht: the hash table to shrink* This function shrinks the hash table to fit, i

Proto:static int rhashtable_shrink(struct rhashtable *ht)

Type:int

Parameter:

Type	Parameter	Name
struct rhashtable *	ht	>mutex.

380

old_tbl = rht_dereference(tbl, >mutex.)

381

nelems = atomic_read( & nelems)

382

size = 0

384

If nelems Then size = undup_pow_of_two - round the given value up to nearest power of two*@n: parameter* round the given value up to the nearest power of two* - the result is undefined when n == 0* - this can be used to initialise global variables from constant data(nelems * 3 / 2)

386

If size < min_size Then size = min_size

389

If size <= size Then Return 0

392

If rht_dereference(future_tbl, >mutex.) Then Return -EEXIST

395

Return rhashtable_rehash_alloc(>mutex., old_tbl, size)
