**Caller**
Name	Describe
ksys_umount	Now umount can handle mount points as well as block devices.* This is important for filesystems which use unnamed block devices.* We now support a flag for forced unmount like the other 'big iron'* unixes
SYSCALL_DEFINE3
do_mount	Flags is a 32-bit value that allows up to 31 non-fs dependent flags to* be given to the mount() call (ie: read-only, no-dev, no-suid etc)
SYSCALL_DEFINE3	Create a kernel mount representation for a new, prepared superblock* (specified by fs_fd) and attach to an open_tree-like file descriptor.
SYSCALL_DEFINE5	Move a mount from one place to another. In combination with* fsopen()/fsmount() this is used to install a new mount and in combination* with open_tree(OPEN_TREE_CLONE [\| AT_RECURSIVE]) it can be used to copy* a mount subtree.
SYSCALL_DEFINE2	pivot_root Semantics:* Moves the root file system of the current process to the directory put_old,* makes new_root as the new root file system of the current process, and sets* root/cwd of all processes which had them on the current root to new_root
