It shows the call stack only, and looks like,,,
nfs_setattr [nfs]
unlock_page
__do_fault
kmap_atomic_prot
fnotify_change
call_notify_change [aufs]
vfsub_fnotify_change [aufs]
vfsub_notify_change [aufs]
aufs_do_setattr [aufs]
aufs_fsetattr [aufs]
:::
Very strange.
I don't know the functions aufs_fsetattr(), aufs_do_setattr() and
vfsub_fnotify_change(). At least, there is no such function in current
and near past aufs source files. Additionally I am unsure they have ever
been.
Is it I that wrote them?
