Linux kernel source tree
2f3017e7cc
Commands like "chmod 0444" mark a file readonly via the attribute flag
(when mapping of mode bits into the ACL are not set, or POSIX extensions
are not negotiated), but they were not reported correctly for stat of
directories (they were reported ok for files and for "ls"). See example
below:
root:~# ls /mnt2 -l
total 12
drwxr-xr-x 2 root root 0 Sep 21 18:03 normaldir
-rwxr-xr-x 1 root root 0 Sep 21 23:24 normalfile
dr-xr-xr-x 2 root root 0 Sep 21 17:55 readonly-dir
-r-xr-xr-x 1 root root 209716224 Sep 21 18:15 readonly-file
root:~# stat -c %a /mnt2/readonly-dir
755
root:~# stat -c %a /mnt2/readonly-file
555
This fixes the stat of directories when ATTR_READONLY is set
(in cases where the mode can not be obtained other ways).
root:~# stat -c %a /mnt2/readonly-dir
555

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.
