Linux kernel modifications for the Kernel Hacking exam
6887037025
With gcc-4.1.2:
net/smc/smc_core.c: In function ‘__smc_buf_create’:
net/smc/smc_core.c:567: warning: ‘bufsize’ may be used uninitialized in this function
Indeed, if the for-loop is never executed, bufsize is used
uninitialized. In addition, buf_desc is stored for later use, while it
is still a NULL pointer.
Before, error handling was done by checking if buf_desc is non-NULL.
The cleanup changed this to an error check, but forgot to update the
preinitialization of buf_desc to an error pointer.
Update the preinitializatin of buf_desc to fix this.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
