When the bts tracer is removed while the traced task is running, the write to clear the bts tracer pointer races with context switch code. Read the tracer once during a context switch. When a new tracer is installed, the bts tracer is set in the ds context before the tracer is initialized in order to claim the context for that tracer. This may result in write accesses using an uninitialized trace configuration when scheduling timestamps have been requested. Store active tracing flags separately and only set active flags after the tracing configuration has been initialized. Reviewed-by:

This makes the defautl ext3 data ordering mode (when no explicit ordering is set) configurable, so as to allow people to default to 'data=writeback' and get the resulting latency improvements. This is a non-issue if a filesystem has been explicitly set to some ordering (with 'tune2fs'). Signed-off-by:

The CAP_KILL check in exit_notify() looks just wrong, kill it. Whatever logic we have to reset ->exit_signal, the malicious user can bypass it if it execs the setuid application before exiting. Signed-off-by:

There are various bits of code here that are unfinished and instead of being harmless either confuse or spew stuff into the logs at higher than debug level. They can and should go away. Also remove the bogus use of tty->lowlatency. We fixed the need for this hack long ago (with the flip buffer rewrite) but people keep copying it into drivers. Signed-off-by:

mxser_check_modem_status is called with tty parameter, so the reference should be increased by callers already -- for ioctl syscall it is held whole time gap since open to close, for interrupt, the reference count is increased in the irq handler. There is no tty_kref_put in that function, so this also fixes a refcounting bug. Signed-off-by:
