Subject: [LKP] [fanotify] 66ba93c0d7f: i6300esb: Unexpected close, not
 stopping watchdog!

FYI, we noticed the below changes on

git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
commit 66ba93c0d7fe63def447ad0afe380307ff9ebcad ("fanotify: don't set FAN_ONDIR implicitly on a marks ignored mask")

When doing LTP test.  Test system hang after doing some fanotify test cases, while system
can run to reboot in the parent comments.
