From e977145aeaad23d443686f2a2d5b32800d1607c5 Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Fri, 21 Apr 2006 23:15:39 +0100 Subject: [RBTREE] Add explicit alignment to sizeof(long) for struct rb_node. Seems like a strange requirement, but allegedly it was necessary for struct address_space on CRIS, because it otherwise ended up being only byte-aligned. It's harmless enough, and easier to just do it than to prove it isn't necessary... although I really ought to dig out my etrax board and test it some time.
