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: NChao Yu <chao2.yu@samsung.com> Signed-off-by: NJaegeuk Kim <jaegeuk@kernel.org>

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.

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. Signed-off-by: NJaegeuk Kim <jaegeuk@kernel.org>

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. Signed-off-by: NJaegeuk Kim <jaegeuk@kernel.org>

If a system wants to reduce the booting time as a top priority, now we can use a mount option, -o fastboot. With this option, f2fs conducts a little bit slow write_checkpoint, but it can avoid the node page reads during the next mount time. Signed-off-by: NJaegeuk Kim <jaegeuk@kernel.org>

This patch simplifies the inline_data usage with the following rule. 1. inline_data is set during the file creation. 2. If new data is requested to be written ranges out of inline_data, f2fs converts that inode permanently. 3. There is no cases which converts non-inline_data inode to inline_data. 4. The inline_data flag should be changed under inode page lock. Signed-off-by: NJaegeuk Kim <jaegeuk@kernel.org>

f2fs_write_begin() doesn't initialize the 'dn' variable if the inode has inline data. However it uses its contents to decide whether it should just zero out the page or load data to it. Thus if we are unlucky we can zero out page contents instead of loading inline data into a page.

Previously, init_inode_metadata does not hold any parent directory's inode page. So, f2fs_init_acl can grab its parent inode page without any problem. But, when we use inline_dentry, that page is grabbed during f2fs_add_link, so that we can fall into deadlock condition like below. INFO: task mknod:11006 blocked for more than 120 seconds.
