You might also try lsof. It will give more information about AFS
files than will fuser. Neither application needs root permission.
Neither needs /vmunix.
Lsof uses the kvm_*() library, so it requires permission to read
/dev/kmem -- e.g., be setgid(sys). Lsof doesn't get kernel symbol
information from /vmunix, but from /dev/ksyms.
Fuser relies on the /dev/kstat interface and the undocumented
utssys() system call, so it doesn't need either /dev/kmem or /vmunix.
The f_user structure, returned by utssys(), limits the information
fuser can provide to process ID, user ID, and file usage. Lsof
reads the kernel file structure, follows it to the vnode, and
follows the vnode to the file-system-specific node structure for
the file. Thus it can provide more information than fuser.
Lsof comes with full source code:
