Revision 90382ed9afeafd42ef193f0eadc6b2a252d6c24d authored by Goldwyn Rodrigues on 24 June 2015, 14:30:32 UTC, committed by NeilBrown on 24 July 2015, 03:37:59 UTC 
Fix read-balancing during node failure
 
During a node failure, We need to suspend read balancing so that the
reads are directed to the first device and stale data is not read.
Suspending writes is not required because these would be recorded and
synced eventually.

A new flag MD_CLUSTER_SUSPEND_READ_BALANCING is set in recover_prep().
area_resyncing() will respond true for the entire devices if this
flag is set and the request type is READ. The flag is cleared
in recover_done().

	  Specifies the default pre-allocated buffer-size in kB for the
	  HD-audio driver.  A larger buffer (e.g. 2048) is preferred
	  for systems using PulseAudio.  The default 64 is chosen just
	  for compatibility reasons.

	  Note that the pre-allocation size can be changed dynamically
	  via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.
