Jaegeuk Kim 1ce86bf6f8 f2fs: fix race conditon on truncation with inline_data ... Let's consider the following scenario. blkaddr[0] inline_data i_size i_blocks writepage truncate NEW X 4096 2 dirty page #0 NEW X 0 change i_size NEW X 0 2 f2fs_write_inline_data NEW X 0 2 get_dnode_of_data NEW X 0 2 truncate_data_blocks_range NULL O 0 1 memcpy(inline_data) NULL O 0 1 f2fs_put_dnode NULL O 0 1 f2fs_truncate NULL O 0 1 get_dnode_of_data NULL O 0 1 *invalid block addr* This patch adds checking inline_data flag during f2fs_truncate not to refer corrupted block indices.
