Hi Ted,

I tried to run this on my end, and I didn't see the errors that you
pointed out. Here's my run:

Failures: ext4/049 generic/459 generic/506 generic/645
Failed 4 of 553 tests
Xunit report: /results/ext4/results-fast_commit/result.xml

END TEST: Ext4 4k block w/fast_commit Wed Apr 30 18:15:26 UTC 2025
-------------------- Summary report
KERNEL:    kernel 6.14.0-rc2-xfstests-perf-gff9ebf4dde0d #31 SMP
PREEMPT_DYNAMIC Sat Apr 12 19:35:39 UTC 2025 x86_64
CMDLINE:   -c fast_commit -g auto

I explicitly also ran the tests were causing error for you and I still
don't see any failures:

Ran: generic/127 generic/241 generic/418
Passed all 3 tests
Xunit report: /results/ext4/results-fast_commit/result.xml
-------------------- Summary report
KERNEL:    kernel 6.14.0-rc2-xfstests-perf-gff9ebf4dde0d #31 SMP

CMDLINE:   -c fast_commit generic/127 generic/241 generic/418

Maybe my patches are conflicting with some other patches that are
being merged? Let's talk about this in tomorrow's call.

Thank you,
Harshad
