Subject: [RBTREE] Update hrtimers to use rb_parent() accessor macro.
X-Git-Tag: v2.6.18-rc1~1104^2~2
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ed198cb49750fd9ec564e9f1df66c10efea605f1;p=linux-2.6

[RBTREE] Update hrtimers to use rb_parent() accessor macro.

Also switch it to use the same method of using off-tree nodes as
everyone else now does -- set them to point to themselves.
