If DAT metadata file block access fails due to corruption of the DAT file or abnormal virtual block numbers held by b-trees or inodes, a kernel warning is generated. This replaces the WARN_ONs by error output, so that a kernel, booted with panic_on_warn, does not panic. This patch also replaces the detected return code -ENOENT with another internal code -EINVAL to notify the bmap layer of metadata corruption. When the bmap layer sees -EINVAL, it handles the abnormal situation with nilfs_bmap_convert_error() and finally returns code -EIO as it should.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
