Revert "printk: wake up all waiters"
This reverts commit 938ba4084abcf6fdd21d9078513c52f8fb9b00d0.
The wait queue @log_wait never has exclusive waiters, so there
is no need to use wake_up_interruptible_all(). Using
wake_up_interruptible() was the correct function to wake all
waiters.
Since there are no exclusive waiters, erroneously changing
wake_up_interruptible() to wake_up_interruptible_all() did not
result in any behavior change. However, using
wake_up_interruptible_all() on a wait queue without exclusive
waiters is fundamentally wrong.
Go back to using wake_up_interruptible() to wake all waiters.
