Make changes to use sysfs_emit in the RDMA code as cocci scripts can not be written to handle _all_ the possible variants of various sprintf family uses in sysfs show functions. While there, make the code more legible and update its style to be more like the typical kernel styles. Miscellanea: o Use intermediate pointers for dereferences o Add and use string lookup functions o return early when any intermediate call fails so normal return is at the bottom of the function o mlx4/mcg.c:sysfs_show_group: use scnprintf to format intermediate strings Link: https://lore.kernel.org/r/f5c9e4c9d8dafca1b7b70bd597ee7f8f219c31c8.1602122880.git.joe@perches.com Signed-off-by: Joe Perches <joe@perches.com> Acked-by: Jack Wang <jinpu.wang@cloud.ionos.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
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.
