Defect/Fix: When outbound detach request is executed in ICS context, synchronization
between this request and Inbound reset request fails and this leads in to a spinlock panic.
Code changes have been done to synchronize both the requests even in ICS context.
• JAGag02647
Symptoms: Unable to allocate Zcom_strbuf buffer for an incoming data block.
Defect/Fix: This problem happens due to a re initialization problem in the linked list, when
the entire buffers are consumed in stream buffer pool. Because of this, freed buffer are not
concatenated to the list and message allocation routine fails to get a buffer for an inbound
message. Code changes are done to take care of the re initialization issue to concatenate the
freed buffers properly.
