trace-cmd
Hi Steven,
I found two small bugs for current trace-cmd, so I fixed those.
1st patch fixes the problem which listen server reader processes abort silently.
2nd patch fixes the problem which trace-cmd cannot record trace data of
multiple buffers in old kernels.
Thank you,

er p->fcr is existing at serial8250_clear_and_reinit_fifos()
- Set fcr = up->fcr in the begging of serial8250_do_set_termios()
Changes in V3:
- Change I/F from ioctl(2) to sysfs(rx_int_trig)
Changed in V2:
- Use _IOW for TIOCSFIFORTRIG definition
- Pass the interrupt trigger value itself

Hi Steven,
Thank you for applying my patches.
I received build warning report from kbuild test bot,
so I fixed it. Would you apply this patch?
Thank you,

Hi Steven,
I found three small bugs for current ftrace/core, so I fixed those.
Would you apply these patches?
Thanks!

Yoshihiro YUNOMAE (3):
trace/event: Return error if ftrace_trace_arrays is empty list
trace/kprobes: Avoid self tests if tracing is disabled on boot up
Current new_instance_create() implements just two fail paths for four
allocation operations. So, it can induce memory leak if new instance
creation failed. This patch fixes it by defining all fail paths and
freeing allocated memories appropriately.

If tracing is disabled on boot up, the kernel should not execute self tests.
In this patch, the kernel checks whether tracing is disabled or not
before executing self tests.
