Subject: Re: [patch 07/26] Add INIT_ARRAY() to kernel.h (updated)
Date: Thursday, January 24, 2008 - 4:54 pm

Add initialization of an array, which needs brackets that would pollute kernel
code, to kernel.h. It is used to declare arguments passed as function parameters
such as:
text_poke(addr, INIT_ARRAY(unsigned char, 0xf0, len), len);

Changelog :
- [len] -> []
- Remove whitespaces.
- Fixed Jan's suggestion which was not checkpatch.pl-safe.
