That certainly doesn't mean that it's not a kernel bug; it just means
that it's a kernel bug that wasn't fixed between 4.19-rc7 and 4.19.
The inline_data feature isn't enabled by default because we're not
100% confidence that it's fully rock solid. We are regularly running
regression testing on that configuration, and while there are some
test failures with inline_data enabled that aren't there with the
default options, none of them have caused processes to get stuck:
ext4/4k: 444 tests, 2 failures, 42 skipped, 4442 seconds
Failures: ext4/034 generic/388
ext4/encrypt: 512 tests, 1 failures, 123 skipped, 2638 seconds
Failures: ext4/034
ext4/dioread_nolock: 443 tests, 2 failures, 42 skipped, 4338 seconds
Failures: ext4/034 generic/388
vs
ext4/adv: 448 tests, 4 failures, 48 skipped, 4149 seconds
Failures: ext4/034 generic/399 generic/477 generic/519
So basically, at the moment I can't really recommend this feature for
general use --- although this particular failure which you've reported
is a new one for me.

Is this true even if you reboot? What if you force an fsck check on the file
system?
