Detailed Description

State data storage for get_thread_transaction_locker_v1_t, get_thread_transaction_locker_v1_t.

This structure provide temporary storage to a transaction locker. The content of this structure is considered opaque, the fields are only hints of what an implementation of the psi interface can use. This memory is provided by the instrumented code for performance reasons.
