real_mount

Type	Parameter	Name
struct vfsmount *	mnt

**Caller**
Name	Describe
follow_up	llow_up - Find the mountpoint of path's vfsmount* Given a path, find the mountpoint of its source file system
follow_dotdot_rcu
__mnt_want_write	__mnt_want_write - get write access to a mount without freeze protection@m: the mount on which to take a write This tells the low-level filesystem that a write is about to be performed to* it, and makes sure that writes are allowed (mnt it read-write)
mnt_clone_write	mnt_clone_write - get write access to a mount@mnt: the mount on which to take a write This is effectively like mnt_want_write, except* it must only be used to take an extra write reference* on a mountpoint that we already know has a write reference
__mnt_drop_write	__mnt_drop_write - give up write access to a mount@mnt: the mount on which to give up write access Tells the low-level filesystem that we are done* performing writes to it. Must be matched with* __mnt_want_write() call above.
__legitimize_mnt	all under rcu_read_lock
mntput
mntget
mnt_clone_internal
may_umount_tree	may_umount_tree - check if a mount tree is busy@mnt: root of mount tree This is called to check if a tree of mounts has any* open files, pwds, chroots or sub mounts that are* busy.
may_umount	may_umount - check if a mount point is busy@mnt: root of mount This is called to check if a mount point has any* open files, pwds, chroots or sub mounts. If the* mount has sub mounts this will return busy* regardless of whether the sub mounts are busy.
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
collect_mounts	Caller should check returned pointer for errors
dissolve_on_fput
drop_collected_mounts
clone_private_mount	lone_private_mount - create a private clone of a path* This creates a new vfsmount, which will be the clone of @path. The new will* not be attached anywhere in the namespace and will be private (i.e. changes
iterate_mounts
do_change_type	rsively change the type of the mountpoint.
__do_loopback
do_loopback	do loopback mount.
do_reconfigure_mnt	Handle reconfiguration of the mountpoint only without alteration of the* superblock it refers to. This is triggered by specifying MS_REMOUNT\|MS_BIND* to mount(2).
do_remount	hange filesystem flags. dir should be a physical root of filesystem.* If you've mounted a non-root directory somewhere and want to do remount* on it - tough luck.
do_move_mount
do_add_mount	add a mount into a namespace's mount tree
do_new_mount_fc	Create a new mount using a superblock configuration and request it* be added to the namespace tree.
finish_automount
mnt_set_expiry	mnt_set_expiry - Put a mount on an expiration list@mnt: The mount to list.@expiry_list: The list to add the mount to.
mount_subtree
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.
path_is_under
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
init_mount_tree
kern_mount
kern_unmount
our_mnt
mnt_may_suid
prepend_path	prepend_path - Prepend path string to a buffer@path: the dentry/vfsmount to report@root: root vfsmnt/dentry@buffer: pointer to the end of the buffer@buflen: pointer to buffer length* The function will first try to write out the pathname without taking
pin_insert
show_vfsmnt
show_mountinfo
show_vfsstat
fsnotify	This is the main call to fsnotify. The VFS calls into hook specific functions* in linux/fsnotify.h. Those functions then in turn call here. Here will call* out to all of the registered fsnotify_group. Those groups can then use the
