For example, we may need to check whether a directory is empty or not before performing any operations on it. In this tutorial, we’ll explore different ways that we can use to determine if a directory is empty.
If this check is done later after the test * of oldbrk with newbrk then it can escape the test and let the data * segment grow beyond its set limit the in case where the limit is * not page aligned -Ram Gupta */ if (check_data_rlimit(rlimit(RLIMIT_DATA), brk, mm->start_brk,...
You can use the "mount" command to check if a directory is mounted on a Linux system. For example, to check if the directory "/mnt/data" is mounted, you can run ? mount | grep "/mnt/data" If the directory is mounted, the command will return information about the mount point, ...

dentry对象保存在slab cache里,这个也叫directory entry cache(or dcahce)。这样就可以快速的寻找一个文件。一个或多个dentry会关联到一个inode上,比如硬链接(hard link)。 路径名查找(pathname lookup) 当我们使用open(), mkdir()等系统调用的时候,需要根据路径名找出对应的VFS对象(inode, dentry等),这个过程就...
