Hi,
I rewrote two TCP_USER_TIMEOUT patches.
I changed the third argument of setsockopt() from 18 to TCP_USER_TIMEOUT.
This revision has the following two merits.
* Improve readability of source
* Even if the definition of TCP_USER_TIMEOUT is changed, it is not affected.
e.g., in the current linux, TCP_USER_TIMEOUT is defined, but even if it is changed to 19, it 'll be available.
Best regards,
