Currently, there are several variables with Boolean type as below: struct f2fs_sb_info { ... int s_dirty; bool need_fsck; bool s_closing; ... bool por_doing; ... } For this there are some issues: 1. there are some space of f2fs_sb_info is wasted due to aligning after Boolean type variables by compiler. 2. if we continuously add new flag into f2fs_sb_info, structure will be messed up. So in this patch, we try to: 1. switch s_dirty to Boolean type variable since it has two status 0/1. 2. merge s_dirty/need_fsck/s_closing/por_doing variables into s_flag. 3. introduce an enum type which can indicate different states of sbi. 4. use new introduced universal interfaces is_sbi_flag_set/{set,clear}_sbi_flag to operate flags for sbi. After that, above issues will be fixed. Signed-off-by: NChao Yu <chao2.yu@samsung.com> Signed-off-by: NJaegeuk Kim <jaegeuk@kernel.org>

This patch fixes to trigger checkpoint with umount flag when kill_sb was called. In kill_sb, f2fs_sync_fs was finally called, but at this time, f2fs can't do checkpoint with CP_UMOUNT. After then, f2fs_put_super is not doing checkpoint, since it is not dirty. So, this patch adds a flag to indicate f2fs_sync_fs is called during umount.

This patch aligns the start block address of a file for direct io to the f2fs's section size. Some flash devices manage an over 4KB-sized page as a write unit, and if the direct_io'ed data are written but not aligned to that unit, the performance can be degraded due to the partial page copies. Thus, since f2fs has a section that is well aligned to FTL units, we can align the block address to the section size so that f2fs avoids this misalignment.

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.

This patch adds two new ioctls to release inmemory pages grabbed by atomic writes. o f2fs_ioc_abort_volatile_write - If transaction was failed, all the grabbed pages and data should be written. o f2fs_ioc_release_volatile_write - This is to enhance the performance of PERSIST mode in sqlite. In order to avoid huge memory consumption which causes OOM, this patch changes volatile writes to use normal dirty pages, instead blocked flushing to the disk as long as system does not suffer from memory pressure.

To improve recovery speed, f2fs try to readahead many contiguous blocks in warm node segment, but for most time, abnormal power-off do not occur frequently, so when mount a normal power-off f2fs image, by contrary ra so many blocks and then invalid them will hurt the performance of mount. It's better to just ra the first next-block for normal condition. Signed-off-by: NChao Yu <chao2.yu@samsung.com> Signed-off-by: NJaegeuk Kim <jaegeuk@kernel.org>

Previoulsy, we used rwlock for nat_entry lock. But, now we have a lot of complex operations in set_node_addr. (e.g., allocating kernel memories, handling radix_trees, and so on) So, this patches tries to change spinlock to rw_semaphore to give CPUs to other threads.

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>

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>

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.
