Linux kernel source tree
40da553f5d
Currently we ignore s_clusters_per_group field in the on-disk superblock if bigalloc feature is not enabled. However e2fsprogs don't even open the filesystem if s_clusters_per_group is invalid. This results in an odd state where kernel happily works with the filesystem while even e2fsck refuses to touch it. Verify that s_clusters_per_group is valid even if bigalloc feature is not enabled to make things consistent. Due to current e2fsprogs behavior it is unlikely there are filesystems out in the wild (except for intentionally fuzzed ones) with invalid s_clusters_per_group counts.

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.
