I observe the fstests test case generic/774 hangs, when I run it for xfs on 8GiB
TCMU fileio devices. It was observed with v6.17 and v6.18-rcX kernel versions.
FYI, here I attach the kernel message log that was taken with v6.18-rc3 kernel
[1]. The hang is recreated in stable manner by repeating the test case a few
times in my environment.

Actions for fix will be appreciated. If I can do any help, please let me know.
