Reprint: https://www.ibm.com/developerworks/cn/linux/l-knldebug/Principle and implementation of dynamic replacement of Linux core functionsWhen debugging a Linux core module, it is sometimes necessary to get real-time access to the execution state of some functions on one of the internal paths, such as seeing if the incoming variable is the desired value to determine if the entire execution process is still normal. Due to the dynamic nature of the sys

When using eclipse, finding replacements may be a tool we often use, but most of them simply look for replacements for simple word text (such as finding replacement warnings), but in complex situations, most people may manually change.For example:/* */Public class configuration/* */{/*/ Private listWhen we encounter the above code, we can easily replace the "/* * * * * * * * * * * * * * * *, but cannot replace the comment like"/* 41 * * ".In fac

We all know this running "adb shell" from the command line was pretty crap, and when using a latter BusyBox version whi CH have coloring support it s ultimately crap.
