The easiest way is patching sys_close() ;-)
But as you likely need a test reproducable on all kernel versions, you
should use some FS that blocks/loops in either fops->flush() or
fops->release(). The easiest way should be FUSE and a custom FUSE
module where you just call sleep() inside of ->release().
Thanks,
