Patch series "nilfs2: prevent unexpected ENOENT propagation". This series fixes potential issues where the result code -ENOENT, which is returned internally when a metadata file operation encouters a hole block, is exposed to user space without being properly handled. Several issues with the same cause leading to hangs or WARN_ON check failures have been reported by syzbot and fixed each time in the past. This collectively fixes the missing -ENOENT conversions that do not cause stability issues and are not covered by syzbot. This patch (of 5): The sufile, a metadata file that holds metadata for segment management, has statistical information in its first block, but if reading this block fails, it receives the internal code -ENOENT and returns it unchanged to the callers. To prevent this -ENOENT from being propagated to system calls, if reading the header block fails, return -EIO (or -EINVAL depending on the context) instead.

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 reStructuredText 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.
