From 2b3cb2e778811a1df99e37fd7c359837501ab103 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Wed, 9 May 2007 02:33:57 -0700 Subject: [PATCH] tg3: use flush_work_keventd() Convert tg3 over to flush_work_keventd(). Remove nasty now-unneeded deadlock avoidance logic. (akpm: bypassed maintainers, sorry. There are other patches which depend on this) Cc: "Maciej W. Rozycki" Cc: David Howells Cc: "David S.
