In the Linux kernel, the following vulnerability has been resolved: f2fs: compress: fix to cover {reserve,release}_compress_blocks() w/ cp_rwsem lock It needs to cover {reserve,release}_compress_blocks() w/ cp_rwsem lock to avoid racing with checkpoint, otherwise, filesystem metadata including blkaddr in dnode, inode fields and .total_valid_block_count may be corrupted after SPO case.
