在文件的所有实例都被释放了之后,内核中的file结构也就会被释放。 View Code 总结归纳: (1)vfsmount,super_block,dentry,inode 结构在内核之中都有一个全局的hash表缓存用来加快访问的速度,每个hash数组存着hash链表将相同种类的结点种类放在同一个链表中,并专门设置一 个成员变量用来访问在hash链表中与之相邻的结...

...在Linux中,文件系统被组织成一个树形结构,称为文件系统层次结构(Filesystem Hierarchy Standard,FHS),该标准规定了Linux操作系统中各级目录的名称和用途,使得Linux.../proc /proc目录是Linux系统中一个特殊的目录,用于提供进程和系统信息的虚拟文件系统。...在/proc目录下,每个进程都有一个对应的子目录,可以...
We may also see aNAS, which is simply a dedicated fileserver machine sharing space via NFS, SMB, or another network file protocol. On the other hand, a SAN uses a protocol like iSCSI or FibreChannel to connect storage over the network on a block level. From Linux’s point of view, it...
