commitb40ebaf638upstream. Commitfb0a387dcd("ext4: limit block allocations for indirect-block files to < 2^32") added code to try to allocate xattr block with 32-bit block number for indirect block based files on the grounds that these files cannot use larger block numbers. It also added BUG_ON when allocated block could not fit into 32 bits. This is however bogus reasoning because xattr block is stored in inode->i_file_acl and inode->i_file_acl_hi and as such even indirect block based files can happily use full 48 bits for xattr block number. The proper handling seems to be there basically since 64-bit block number support was added. So remove the bogus limitation and BUG_ON.

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.
