Rohit 1a5b472bde Security: smack: replace kzalloc with kmem_cache for inode_smack ... The patch use kmem_cache to allocate/free inode_smack since they are alloced in high volumes making it a perfect case for kmem_cache. As per analysis, 24 bytes of memory is wasted per allocation due to internal fragmentation. With kmem_cache, this can be avoided. Accounting of memory allocation is below : total slack net count-alloc/free caller Before (with kzalloc) 1919872 719952 1919872 29998/0 new_inode_smack+0x14 After (with kmem_cache) 1201680 0 1201680 30042/0 new_inode_smack+0x18 >From above data, we found that 719952 bytes(~700 KB) of memory is saved on allocation of 29998 smack inodes.
