VFS_MOUNT -- mount a file system
VFS_MOUNT(struct mount *mp, char *path, caddr_t data,
struct nameidata *ndp, struct thread *td);
Mount a file system into the system's namespace.
Its arguments are:
mp Structure representing the file system.
path Pathname where the file system is being mounted.
data File system specific data. This should be read into the kernel
ndp Contains the result of a namei(9) call on the pathname of the
td Thread which is mounting the file system.
This is called both to mount new file systems and to change the
attributes of an existing file system. If the MNT_UPDATE flag is set in
mp->mnt_flag then the file system should update its internal state from
the value of mp->mnt_flag. This can be used, for instance, to convert a
read-only file system to read-write. It is also used by mountd(8) to
update the NFS export information for the file system.
If the MNT_UPDATE flag is not specified, then this is a newly mounted
file system. The file system code should allocate and initialize any
private data needed to represent the file system (it can use the
mp->mnt_data field to store this information).
