Subject: [PATCH 0/2] cache: fix cache logic not go into invalid state
Date: Tue, 17 Sep 2013 15:29:27 +0900	[thread overview]
Message-ID: <20130917062606.4671.40617.stgit@localhost6.localdomain6> (raw)

I faced failure of sadump phys_base calculation and found a bug in
cache.c causes it. Due to the bug, cache_alloc() returns NULL forever
throughout execution. The fix is the 2nd patch. During the
investigation I also found a lack of malloc() allocation failure
check. The fix is the 1st patch. Primary is the 2nd one.

I built this patch set on top of devel branch.

      cache: allocate buffers at initialization to detect malloc() failure
      cache: reuse entry in pending list
