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. [1] https://lore.kernel.org/linux-xfs/cmk52aqexackyz65phxgme55a3tdrermo3o4skr4lo4pwvvvcp@jmcblnfikbp2/#t 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. generic/765 [not run] write atomic not supported by this block device generic/767 11s generic/768 13s generic/769 13s generic/770 32s generic/773 [not run] write atomic not supported by this block device generic/774 (skipped) generic/775 293s generic/776 [notrun] write atomic not supported by this block device generic/778 48s xfs/838 [not run] External volumes not in use, skipped this test 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.
