[PATCH v3 2/7] net: remove old tcp_optlen function
The tcp_optlen() function returns a potential *negative* unsigned. In the only two existing files using the old tcp_optlen() function, clean up confusing and inconsistent mixing of both byte and word offsets, and other coding style issues. Document assumptions. Quoth David Miller: This is transmit, and th... 14 Feb 2010 01:58
[PATCH v3 1/7] net: tcp_header_len_th and tcp_option_len_th
Redefine two TCP header functions to accept TCP header pointer. When subtracting, return signed int to allow error checking. These functions will be used in subsequent patches that implement additional features.

[PATCH 08/10] ARM: ftrace: fix and update dynamic ftrace
This adds mcount recording and updates dynamic ftrace for ARM to work with the new ftrace dyamic tracing implementation. It also adds support for the mcount format used by newer ARM compilers. With dynamic tracing, mcount() is implemented as a nop. Callsites are patched on startup with nops, and dynamically pat... 13 Feb 2010 14:55
