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.

V2 -> V3: Make the From and SoB match. V1 -> V2: Restore buffer_size_kb outside of awk script.
Thank you. Applied to linux-kselftest fixes branch. I will send this up for the next rc.
