Curretly in function generic_listxattr the for_each_xattr_handler loop checks err and will return out of the function if err is non-zero. It's impossible for err to be non-zero at the end of the function where err is checked again for a non-zero value. The final non-zero check is therefore redundant and can be removed. Also move the declaration of err into the loop. Signed-off-by: Colin Ian King <colin.i.king@gmail.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
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.
