Description

This issue was created by maloo for Andreas Dilger <[e-mail]>

This issue relates to the following test suite run:
https://testing.whamcloud.com/test_sets/a8aa2796-5d0c-4650-a096-0e09a2c7a98e

test_56x started failing on 2023-11-18 with the following error:

migrate failed rc = 22

Test session details:
clients: https://build.whamcloud.com/job/lustre-master/4489 - 5.14.0-284.30.1.el9_2.x86_64
servers: https://build.whamcloud.com/job/lustre-b2_12/164 - 3.10.0-1160.49.1.el7_lustre.x86_64

Patch https://review.whamcloud.com/51126 "LU-13805 llite: Implement unaligned DIO connect flag" was landed on 2023-11-18 without any actual interop testing.

I now see pretty regular sanity test_56x failures with "-22 = -EINVAL" being returned from "lfs migrate" during interop testing and it looks from the debug log that this patch is the culprit, even though the servers are running ldiskfs:
