JFS: Fix race waking up jfsIO kernel thread It's possible for a journal I/O request to be added to the log_redrive queue and the jfsIO thread to be awakened after the thread releases log_redrive_lock but before it sets its state to TASK_INTERRUPTIBLE. The jfsIO thread should set the state before giving up the spinlock, so the waking thread will really wake it. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>
