      f2fs: introduce struct inode_management to wrap inner fields · 67298804
      由 Chao Yu 提交于 
      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 */
	...
}

      f2fs: remove unneeded check code with option in f2fs_remount · aba291b3
      由 Chao Yu 提交于 
      Because we have checked the contrary condition in case of "if" judgment, we do
not need to check the condition again in case of "else" judgment. Let's remove
it.

      f2fs: avoid unable to restart gc thread in remount · 6c029932
      由 Chao Yu 提交于 
      In f2fs_remount, we will stop gc thread and set need_restart_gc as true when new
option is set without BG_GC, then if any error occurred in the following
procedure, we can restore to start the gc thread.
But after that, We will fail to restore gc thread in start_gc_thread as BG_GC is
not set in new option, so we'd better move this condition judgment out of
start_gc_thread to fix this issue.

      f2fs: convert inline_data when i_size becomes large · 92dffd01
      由 Jaegeuk Kim 提交于 
      If i_size becomes large outside of MAX_INLINE_DATA, we shoud convert the inode.
Otherwise, we can make some dirty pages during the truncation, and those pages
will be written through f2fs_write_data_page.
At that moment, the inode has still inline_data, so that it tries to write non-
zero pages into inline_data area.

      f2fs: fix deadlock to grab 0'th data page · 764d2c80
      由 Jaegeuk Kim 提交于 
      The scenario is like this.

One trhead triggers:
  f2fs_write_data_pages
    lock_page
    f2fs_write_data_page
      f2fs_lock_op  <- wait

The other thread triggers:
  f2fs_truncate
    truncate_blocks
      f2fs_lock_op
        truncate_partial_data_page
          lock_page  <- wait for locking the page

This patch resolves this bug by relocating truncate_partial_data_page.
This function is just to truncate user data page and not related to FS
consistency as well.
And, we don't need to call truncate_inline_data. Rather than that,
f2fs_write_data_page will finally update inline_data later.
