Hi Ritesh,
I haven't had a chance to dig into the test failures yet, but FYI....
when I ran the auto test group in xfstests, I saw failures for
generic/219, generic 273, and generic/476 --- these errors did not
show up when running using a standard 4k blocksize on x86, and they
also did not show up when running dioread_nolock using a 4k blocksize.
Sorry about that. Were these 3 the only tests you saw to be failing,
or there were more?
So I tried running "generic/219 generic/273 generic/476" 30 times,
using in a Google Compute Engine VM, using gce-xfstests, and while I
wasn't able to get generic/219 to fail when run in isolation,
generic/273 seems to fail quite reliably, and generic/476 about a
third of the time.
How much testing have you done with these patches?
I did test "quick" group of xfstests & ltp/fsx tests with the posted
version. And had tested a full suite of xfstests with one of my previous
version.
I guess I was comparing against 1K blocksize without dioread_nolock.
But as I think more about it, I may need to compare against vanilla
kernel with 1K blocksize even without dioread_nolock. Since there may
be some changes in blocksize < pagesize path with this patch.
Also I see these tests(generic/273 & generic/476) are not part
of quick group. Let me check more about these failing tests at my end.
Thanks for your inputs.
