Kernel-mode device drivers refer to a file by its object name. This name is \DosDevices together with the full path of the file. For example, the object name of the C:\Windows\Example.txt file is \DosDevices\C:\Windows\Example.txt. Then the object name is encapsulated into an OBJECT_...
Linux 中定义最大文件路径 PATH_MAX 为 4096,传输的文件路径可能很长,很浪费资源。 为了解决这些问题,NFS 引入了 file handle 这个概念。file handle (fh) 也叫 file identifier (fid)。file handle 默认包含 inode number (ino) 和 inode generation (igeneration)。

=> sys_read => system_call_fastpath 2.2 通过TRACE_EVENT定义 trace event 内核或驱动模块可以定义自己的静态trace event。定义代码可以放在include/trace/events/或者驱动目录下。 在Kernel 4.14.74的典型运行时系统中,有1000+的trace event。 Trace Event是用include/linux/tracepoint.h提供的宏接口来定义的。宏...
RtlCreateRegistryKey Adds a key object in the registry along the given relative path. RtlQueryRegistryValues Gives a driver-supplied callback read-only access to the entries for a specified value name, along a specified relative path, in the registry, after the callback routine is given control...
