Subject: [2.5 patch] kill include/linux/compatmac.h
Date: Fri, 21 Mar 2003 22:43:34 +0100	[thread overview]
Message-ID: <20030321214334.GP6940@fs.tum.de> (raw)

include/linux/compatmac.h is quite useless. The idea behind this file is 
IMHO not bad but it's too outdated to be useful.

The patch below removes compatmac.h and all #include's of it.

The only file using the #define's from compatmac.h was 
drivers/char/sx.c, the patch expands these #define's.

After this the only effect of compatmac.h was the #include of some other 
header files. The only file that actually needed such an #include was 
drivers/char/applicom.c that needed linux/version.h. This is resolved by 
removing some 2.2 compatibility code from applicom.c.

I've tested the compilation with 2.5.65.

-   * This header tries to allow you to write 2.3-compatible drivers, 
-   * but (using this header) still allows you to run them on 2.2 and 
-   * 2.0 kernels. 
-   *
-   * Sometimes, a #define replaces a "construct" that older kernels
-   * had. For example, 
-   *
-   *       DECLARE_MUTEX(name);
-   *
-   * replaces the older 
-   *
-   *       struct semaphore name = MUTEX;
-   *
-   * This file then declares the DECLARE_MUTEX macro to compile into the 
-   * older version. 
-   * 
-   * In some cases, a macro or function changes the number of arguments.
-   * In that case, there is nothing we can do except define an access 
-   * macro that provides the same functionality on both versions of Linux. 
-   * 
-   * This is the case for example with the "get_user" macro 2.0 kernels use:
-   *
-   *          a = get_user (b);
-   *  
-   * while newer kernels use 
-   * 
-   *          get_user (a,b);
-   *
-   * This is unfortunate. We therefore define "Get_user (a,b)" which looks
-   * almost the same as the 2.2+ construct, and translates into the 
-   * appropriate sequence for earlier constructs. 
-   * 
-   * Supported by this file are the 2.0 kernels, 2.2 kernels, and the 
-   * most recent 2.3 kernel. 2.3 support will be dropped as soon when 2.4
-   * comes out. 2.0 support may someday be dropped. But then again, maybe 
-   * not. 
-   *
-   * I'll try to maintain this, provided that Linus agrees with the setup. 
-   * Feel free to mail updates or suggestions.
