A user reported an error where we hit an assertion due to deleting a key in an internal snapshot node, when deleting a dirent that points to a nonexisting inode. We try to avoid doing updates to keys for internal snapshot nodes, but upon inspection of the places where we remove dirents in fsck it appears BTREE_UPDATE_INTERNAL_SNAPSHOT_NODE is correct for all of them: either the target dirent doesn't exist, or it's a directory with multiple dirents pointing to it.

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.
