commit a5336d6bb2d02d0e9d4d3c8be04b80b8b68d56c8 upstream. In commit 27c14b5daa82 we started tracking the last inode seen during an inode walk to avoid infinite loops if a corrupt inobt record happens to have a lower ir_startino than the record preceeding it. Unfortunately, the assertion trips over the case where there are completely empty inobt records (which can happen quite easily on 64k page filesystems) because we advance the tracking cursor without actually putting the empty record into the processing buffer. Fix the assert to allow for this case. Reported-by: zlang@redhat.com Fixes: 27c14b5daa82 ("xfs: ensure inobt record walks always make forward progress") Signed-off-by: Darrick J.

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.
