CONFIG_DEBUG_SLAB
Each byte of allocated memory is set to 0xa5 before being handed to the caller and then set to 0x6b when it is
freed.
P116/636
Finally, when looking at oops listings, always be on the lookout for the “slab poisoning”
values discussed at the beginning of this chapter. Thus, for example, if you get a
kernel oops where the offending address is 0xa5a5a5a5, you are almost certainly forgetting to initialize dynamic memory somewhere.
O'Reilly FTP 站点可下载， misc-progs, 是的，这个包含在 examples 里。
另外， Page 595/636中提到， 可以用 repatch 程序来检查单个文件在不同内核补丁中是被如何修改的，还没看到这个文件？
