From 3676347a5e216a7fec7f8eedbbcf8bed6b9c4e40 Mon Sep 17 00:00:00 2001 From: Peter Osterlund Date: Tue, 6 Sep 2005 15:16:42 -0700 Subject: [PATCH] kill bio->bi_set Jens: ->bi_set is totally unnecessary bloat of struct bio. Just define a proper destructor for the bio and it already knows what bio_set it belongs too. Peter: Fixed the bugs.
