commit775c5033a0upstream. Commit5d069dbe8a("fuse: fix bad inode") replaced make_bad_inode() in fuse_iget() with a private implementation fuse_make_bad(). The private implementation fails to remove the bad inode from inode cache, so the retry loop with iget5_locked() finds the same bad inode and marks it bad forever. kmsg snip: [ ] rcu: INFO: rcu_sched self-detected stall on CPU ...

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.
