When we find an unreachable inode, we now reattach it in the oldest version that needs to be reattached (thus avoiding redundant work reattaching every single version), and we now fix up inode -> dirent backpointers in newer versions as needed - or white out the reattaching dirent in newer versions, if the newer version isn't supposed to be reattached. This results in the second verify fsck now passing cleanly after repairing on a user-provided filesystem image with thousands of different snapshots.

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 reStructuredText 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.
