f2fs: keep dirty inodes selectively for checkpoint

2016-11-23T20:11:08+00:00

This is to avoid no free segment bug during checkpoint caused by a number of dirty inodes. The case was reported by Chao like this. 1. mount with lazytime option 2. fill 4k file until disk is full 3. sync filesystem 4. read all files in the image 5. umount In this case, we actually don't need to flush dirty inode to inode page during checkpoint.

f2fs: avoid mark_inode_dirty

Let's check inode's dirtiness before calling mark_inode_dirty. Signed-off-by: Jaegeuk Kim

f2fs: remove syncing inode page in all the cases

2016-06-03T01:05:12+00:00

This patch reduces to call them across the whole tree. - sync_inode_page() - update_inode_page() - update_inode() - f2fs_write_inode() Instead, checkpoint will flush all the dirty inode metadata before syncing node pages. Note that, this is doable, since we call mark_inode_dirty_sync() for all inode's field change which needs to update on-disk inode as well. Signed-off-by: Jaegeuk Kim

f2fs: call mark_inode_dirty_sync for i_field changes

f2fs: remove unneeded pointer conversion

2016-02-23T00:07:23+00:00

There are redundant pointer conversion in following call stack: - at position a, inode was been converted to f2fs_file_info. - at position b, f2fs_file_info was been converted to inode again. - truncate_blocks(inode,..) - fi = F2FS_I(inode) ---a - ADDRS_PER_PAGE(node_page, fi) - addrs_per_inode(fi) - inode = &fi->vfs_inode ---b - f2fs_has_inline_xattr(inode) - fi = F2FS_I(inode) - is_inode_flag_set(fi,..) In order to avoid unneeded conversion, alter ADDRS_PER_PAGE and addrs_per_inode to acept parameter with type of inode pointer. Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim
