f2fs: introduce struct inode_management to wrap inner fields
Now in f2fs, we have three inode cache: ORPHAN_INO, APPEND_INO, UPDATE_INO, and we manage fields related to inode cache separately in struct f2fs_sb_info for each inode cache type. This makes codes a bit messy, so that this patch intorduce a new struct inode_management to wrap inner fields as following which make codes more neat. /* for inner inode cache management */ struct inode_management { struct radix_tree_root ino_root; /* ino entry array */ spinlock_t ino_lock; /* for ino entry lock */ struct list_head ino_list; /* inode list head */ unsigned long ino_num; /* number of entries */ }; struct f2fs_sb_info { ... struct inode_management im[MAX_INO_ENTRY]; /* manage inode cache */ ... } Signed-off-by: Chao Yu <chao2.yu@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
