Linux中实现mount操作需要一定的代码量,下面对Linux VFS Mount代码进行分析说明,整个分析过程按照mount操作函数调用流程进行。代码分析基于Linux-3.2版本。当用户在用户层执行mount命令时,会执行系统调用从用户态陷入linux内核,执行如下函数(namespace.c): SYSCALL_DEFINE5(mount, char __user *, dev_name, char __us...

mount switches to the mount namespace when it reads /etc/fstab, writes /etc/mtab: (or writes to _/run/mount) and calls the mount(2) system call, otherwise it runs in the original mount namespace. This means that the target namespace does not have to contain any libraries or other ...
Propagation here means that the same mount or unmount will automatically occur under all of the other mount points in the peer group. Conversely, mount and unmount events that take place under peer mount points will propagate to this mount point. MS_PRIVATE Make this mount point private. ...
Other systems such as Debian don’t ship tmp.mount in a directly-usable location; this is why you need to copy it to /etc/systemd/system if you want to use it. This has the unfortunate side-effect of creating a full override of tmp.mount in /etc, which means that if the systemd ...
In Linux, "mounting" a drive means making it accessible to the system. When you plug in an external drive, Linux detects it, but you need to tell the system where to “attach” it in the file system. This is done by creating amount point(a directory) and linking the drive to it. ...
Multiple file systems can appear in a comma-separated list. The type names come from the /proc/mounts file, rather than /etc/fstab, which means that some file system names may differ, such as nfs4 versus nfs. Use the file system names from the /proc/mounts file. -v, --verbose: ...
