From 062920734c0de9dd4f0a9bdc36fdcabc2751eb34 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Mon, 29 Dec 2014 15:56:18 +0800 Subject: f2fs: reuse inode_entry_slab in gc procedure for using slab more effectively There are two slab cache inode_entry_slab and winode_slab using the same structure as below: struct dir_inode_entry { struct list_head list; /* list head */ struct inode *inode; /* vfs inode pointer */ }; struct inode_entry { struct list_head list; struct inode *inode; }; It's a little waste that the two cache can not share their memory space for each other. So in this patch we remove one redundant winode_slab slab cache, then use more universal name struct inode_entry as remaining data structure name of slab, finally we reuse the inode_entry_slab to store dirty dir item and gc item for more effective.
