[bug report] fstests generic/774 hang again

[Shin'ichiro Kawasaki <shinichiro.kawasaki@wdc.com>]

I observe the fstests test case generic/774 hangs, when I run it for xfs on 8GiB
TCMU fileio devices. Actually I once reported this hang symptom in last October,
and Darrick and John kindly took some actions [1]. Since then, the hang
disappeared and I have not observed the hang almost one year. However, my test
system started reporting the hang again last week.

FYI, here I attache the kernel message [2]. I observed the hang last week with
the kernel on the xfs/for-next branch at the commit 0ca15a1a1151 ("xfs: remove
an extra cast in xfs_file_compat_ioctl"). Today, I tried again with the kernel
at current xfs/for-next branch tip 4266ffdfd7cb ("xfs: remove an extra cast in
xfs_file_compat_ioctl"), and observed the hang again. The hang can be recreated
in stable manner by repeating the test case 20 times or so.

I also tried other test cases in atmoicwrites group, and observed no failure.

 xfs/839            [not run] XFS error injection requires CONFIG_XFS_DEBUG
 xfs/840            [not run] write atomic not supported by this block device

Action for fix will be appreciated. If I can do anything on my test node, please
let me know.
