Ryusuke Konishi 1ce784ddfb nilfs2: do not propagate ENOENT error from nilfs_btree_propagate() 
[ Upstream commit 8e39fbb1ed ]

In preparation for writing logs, in nilfs_btree_propagate(), which makes
parent and ancestor node blocks dirty starting from a modified data block
or b-tree node block, if the starting block does not belong to the b-tree,
i.e.  is isolated, nilfs_btree_do_lookup() called within the function
fails with -ENOENT.

In this case, even though -ENOENT is an internal code, it is propagated to
the log writer via nilfs_bmap_propagate() and may be erroneously returned
to system calls such as fsync().

Fix this issue by changing the error code to -EINVAL in this case, and
having the bmap layer detect metadata corruption and convert the error
code appropriately.

README 

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.
