Hi, This release will containing the following stability enhancements: - Finish CFS zap caches implementation; increase CFS performance. - Fix CFS page read missing pgbase; possible read corruption. - Optimize CFS remote short read server-side. - Fix CFS failover livelock and races. - CFS cnode lists traversal to use Linux list macros; cleaner. - CFS fh lookup to use generic Linux code to find cached entry; cleaner. - CFS file read/write no longer obtains DLM token; up to userspace to request POSIX locks; SHM read/write is now lock free. - CFS isize to be SMP / preempt safe. - Fix CFS failover of hard mounts can block processes; symptom high I/O wait when little I/O activity. - Optimization of ICS object array allocation; reduce memory operations. - VPROC zombie to reparent to child reaper process; fix stale zombie reparent to init; carry over POSIX spec from base. - Address various NSC key services possible races in nodedown code. - DRBD reduce contention in OpenSSI code path and upgrade to base drbd-0.7.25 package.
