Casey Schaufler 4e328b0888 Smack: Create smack_rule cache to optimize memory usage ... This patch allows for small memory optimization by creating the kmem cache for "struct smack_rule" instead of using kzalloc. For adding new smack rule, kzalloc is used to allocate the memory for "struct smack_rule". kzalloc will always allocate 32 or 64 bytes for 1 structure depending upon the kzalloc cache sizes available in system. Although the size of structure is 20 bytes only, resulting in memory wastage per object in the default pool. For e.g., if there are 20000 rules, then it will save 240KB(20000*12) which is crucial for small memory targets.
