From 2c36ddeda7f04c085d9a612cf8dab5f0a1cd5224 Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Sat, 10 Feb 2007 18:37:33 +1100 Subject: [PATCH] [XFS] Remove unused arguments from the XFS_BTREE_*_ADDR macros. It makes it incrementally clearer to read the code when the top of a macro spaghetti-pile only receives the 3 arguments it uses, rather than 2 extra ones which are not used. Also when you start pulling this thread out of the sweater (i.e. remove unused args from XFS_BTREE_*_ADDR), a couple other third arms etc fall off too. If they're not used in the macro, then they sometimes don't need to be passed to the function calling the macro either, etc.... Patch provided by Eric Sandeen (sandeen@sandeen.net).
