Description David Binderman 2012-06-26 20:43:01 UTC 
I just ran the cppcheck static analysis tool over the source code
of the Linux kernel. It said

[linux-3.5-rc3/arch/xtensa/kernel/process.c:280]: (warning, inconclusive) Using size of pointer elfregs instead of size of its data.

The source code is

    memset(elfregs, 0, sizeof (elfregs));

Suggest

    memset(elfregs, 0, sizeof (*elfregs));

might be better code.
