I'll take a look. The reason for the objdump was to try to work out
where in xfs_rename we were erroring out, but in your case:
xfs_rename+0x5ac/0x5af
I guess it's the trans_cancel at the very end of the function on the
goto <blah>: error cases.
Is there any chance you could instrument xfs_rename so that for every
goto abort_return and goto error_return you add a printk so we know
which one you hit?
Maybe something like:
printk("line %s error %d\n", __LINE__, error);
just before each goto, with appropriate braces {} sprinkled in as necessary?
I can send a patch if that helps.
Sorry for the brute-force debugging but not at all sure yet what this
may be.
Thanks,
