glusterd rebalance: handle a race condition while starting a rebalance

2011-08-04T05:32:39+00:00

due to the race, there was a possibility of having two (or more) threads doing
glusterd_defrag_start(), which would cause different thread to access same
pointer, and at some point making it NULL, causing other threads to crash with
SEGV.

Also removed unused rename related code.

performance/quick-read: Handle unwinding of frame

2011-07-29T08:29:04+00:00

 corresponding to read fop properly, while validating cache.

  - there was a possibility of double unwind in case of errors.
  - use a new frame to do open in fd-based fops.
    In case of errors, qr_resume_pending_ops will be called to resume all the
    fops waiting on open. Hence if we use frame corresponding to fop (without
    creating a new one), there is a possibility of frame being freed by the
    time open would've returned to quick-read.
