Before this patch, function do_gfs2_set_flags checked if the append and immutable flags were being set while already set. If so, error -EPERM was given. There's no reason why these two flags should be mutually exclusive, and if you set them separately, you will, in essence, set one while it is already set. For example: chattr +a /mnt/gfs2/file1 chattr +i /mnt/gfs2/file1 The first command sets the append-only flag. Since they are additive, the second command sets the immutable flag AND append-only flag, since they both coexist in i_diskflags. So the second command should not return an error. This bug caused xfstests generic/545 to fail. This patch simply removes the invalid checks. I also eliminated an unused parm from do_gfs2_set_flags.

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.
