I would be really surprised if it was... Could you slap the following
into __fput():
struct mount *m = real_mount(mnt);
if (unlikely(!m->mnt_ns)) {
printk(KERN_INFO "type = %s",
mnt->mnt_sb->s_type->name);
WARN_ON(1);
}
and see what it catches? That'll need #include "fs/mount.h" in
fs/file_table.c to compile...
