open-behind: propagate errors from ob_wake_cbk

2013-09-10T00:19:51+00:00

If opening fd in background fails, then remember the error and
fail all further calls on the fd.

Use the newly introduced call_unwind_error() function from
call-stub cleanup to fail the future calls.

open-behind: translator to perform open calls in background

2013-02-06T21:16:08+00:00

This is functionality peeled out of quick-read into a separate
translator.

Fops which modify the file (where it is required to perform the
operation on the true fd) will trigger and wait for the backend
open to succeed and use that fd.

Fops like fstat() readv() etc. will use anonymous FD (configurable)
when original fd is unopened at the backend.
