Name:smk_find_entry - find a label on the list, return the list entry*@string: a text string that might be a Smack label* Returns a pointer to the entry in the label list that* matches the passed string or NULL if not found.

Proto:struct smack_known *smk_find_entry(const char *string)

Type:struct smack_known

Parameter:

TypeParameterName
const char *string
427  hash = Version 2: One word (32 or 64 bits) at a time.* If CONFIG_DCACHE_WORD_ACCESS is defined (meaning * exists, which describes major Linux platforms like x86 and ARM), then* this computes a different hash function much faster.
428  head = smack_known_hash[hash & (SMACK_HASH_SLOTS - 1)]
430  hlist_for_each_entry_rcu - iterate over rcu list of given type*@pos: the type * to use as a loop cursor.*@head: the head for your list.*@member: the name of the hlist_node within the struct.(skp, head, smk_hashed)
431  If strcmp(smk_known, string) == 0 Then Return skp
434  Return NULL
