Changing xattr of a temp file will trigger following assertion failed and make ubifs turn into readonly filesystem: ubifs_assert_failed [ubifs]: UBIFS assert failed: host->i_nlink > 0, in fs/ubifs/journal.c:1801 Reproducer: 1. fd = open(__O_TMPFILE) 2. fsetxattr(fd, key, value2, XATTR_CREATE) 3. fsetxattr(fd, key, value2, XATTR_REPLACE) Fix this by removing assertion 'nlink > 0' for host inode.

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.
