When /sys/kernel/tracing/buffer_size_kb is less than 12KB,
the test_multiple_writes test will stall and wait for more
input due to insufficient buffer space.

Check current buffer_size_kb value before the test. If it is
less than 12KB, it temporarily increase the buffer to 12KB,
and restore the original value after the tests are completed.

Shuah,

Care to take this through your tree? It does fix a bug so it likely should
go into the rc releases and not wait for the next merge window.

Yes I can take this through and send this for rc5 or rc6.
But first the following warning needs fixing before I can
apply the patch

WARNING: From:/Signed-off-by: email address mismatch: 'From: Fushuai Wang [off-list ref]' != 'Signed-off-by: Fushuai Wang [off-list ref]'

Fushuai, please send me v3

thanks,
