Niu, could you please run this test locally to try and debug it. I'm repeatedly seeing IO errors running sanity.sh test_27[opqv] during file object creations running on a RHEL6 kernel.

Thanks, Sarah. The log shows that AS_ENOSPC was set on the proper i_mapping, and I can't tell why it's not transfered to -ENOSPCE in wait_on_page_writeback_range() from the kernel code.
