Subject: nfs mmap adventure (was: 2.6.23-mm1)

Date: Monday, October 15, 2007 - 5:28 am

I get funny SIGBUS' like so:

fault
  if (->page_mkwrite() < 0)
    nfs_vm_page_mkwrite()
      nfs_write_begin()
        nfs_flush_incompatible()
          nfs_wb_page()
            nfs_wb_page_priority()
              nfs_sync_mapping_wait()
                nfs_wait_on_request_locked()
                  nfs_wait_on_request()
                    nfs_wait_bit_interruptible()
                      return -ERESTARTSYS
    SIGBUS

trying to figure out what to do about this...
