The same to commit <36de928641ee4> (ext4: propagate errors up to ext4_find_entry()'s callers') in ext4, also return error instead of NULL pointer in case of some error happens in ext2_find_entry() (e.g. -ENOMEM or -EIO). This could avoid a negative dentry cache entry installed even it failed to read directory block due to IO error.

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.
