The first patch fixes a problem with unusual hardware re-ordering whilst the second fixes a problem with unusual compiler re-ordering. Cheers, Will --->8 Will Deacon (2): locking/qspinlock: Ensure node is initialised before updating prev->next locking/qspinlock: Ensure node->count is updated before initialising node kernel/locking/qspinlock.c | 21 +++++++++++++++------ 1 file changed, 15 insertions(+), 6 deletions(-) -- 2.1.4
