I have a 1 GB jazz drive. The jazz disk is used daily, both at home and at work on my Win 98 Server. So, I have to keep it in vfat format, which is fine because Linux rocks and will read it no problem. :-) However, I can't just stick the disk in the drive and open up the jazz folder in my mnt...

vfs_hooks_unmount
VFS_HOOKS(9) BSD Kernel Developer's Manual VFS_HOOKS(9)NAME
vfs_hooks, vfs_hooks_unmount -- VFS hooks interface
SYNOPSIS
#include <sys/param.h>
#include <sys/mount.h>
void
vfs_hooks_unmount(struct mount *mp);
DESCRIPTION
The VFS hooks interface provides a way for different kernel subsystems to attach custom functions to specific VFS operations. This enforces
code separation by keeping the VFS's core sources uncluttered and makes all subsystem functionality reside in a single place. As an example,
this interface is used by the NFS server code to automatically handle the exports list for each mount point.
Hooks are described by a struct vfs_hooks object, as seen below:
struct vfs_hooks {
int (*vh_unmount)(struct mount *);
};
For simplicity, each field is named after the VFS operation it refers to. The purpose of each member function, alongside some important
notes, is shown below:
vh_unmount(mp)
This hook is executed during the unmount process of a file system.
For more information about the purpose of each operation, see vfsops(9). Note that any of these fields may be a null pointer.
After the definition of a struct vfs_hooks object, the kernel has to add it to the vfs_hooks link set using the VFS_HOOKS_ATTACH(struct
vfs_hooks *) macro.
Please note that this interface is incomplete on purpose to keep it in its smallest possible size (i.e., do not provide a hook that is not
used). If you feel the need to hook a routine to a VFS operation that is not yet supported by this interface, just add it to the files
described in CODE REFERENCES.
FUNCTIONS
The following functions are provided to the VFS code to run the hooked functions:
vfs_hooks_unmount(mp)
Runs all hooks for the VFS unmount operation. Given that these operations shall not fail, it returns void.
CODE REFERENCES
The VFS hooks interface is implemented within the files sys/kern/vfs_hooks.c and sys/sys/mount.h.
SEE ALSO intro(9), vfs(9), vfsops(9)HISTORY
The VFS hooks interface appeared in NetBSD 4.0.
