22:22:02 2023 +0900 nilfs2: prevent WARNING in nilfs_dat_commit_end() If nilfs2 reads a corrupted disk image and its DAT metadata file contains invalid lifetime data for a virtual block number, a kernel warning can be generated by the WARN_ON check in nilfs_dat_commit_end() and can panic if the kernel is booted with panic_on_warn. This patch avoids the issue with a sanity check that treats it as an error. Since error return is not allowed in the execution phase of nilfs_dat_commit_end(), this inserts that sanity check in nilfs_dat_prepare_end(), which prepares for nilfs_dat_commit_end(). As the error code, -EINVAL is returned to notify bmap layer of the metadata corruption. When the bmap layer sees this code, it handles the abnormal situation and replaces the return code with -EIO as it should.
