Lai, could you please take a look at this.  It failed 12x last week, which isn't a huge number given how often sanity.sh is run, but it looks like a real defect and not a test script issue.

Maloo test results search shows this occurs on ZFS backend only, and it failed because the ORPHAN flag is read on the target stripe of migrating directory, I'm afraid its inode attr may not be initialized correctly.

00080000:00000040:1.0:1686430631.310794:0:327942:0:(osd_object.c:1034:osd_attr_get()) lustre-MDT0001: set orphan flag on [0x240002340:0x20:0x0] (0x8877f/0x0)

it shows inode->i_flags has ORPHAN set, which should not happen, because this flag should be set on obj->oo_lma_flags (which is 0 here).
