What?
Propagate
sys_devandmem_flagsin UCM memory events and removeUCS_MEM_FLAG_NEEDS_QUERY.Why?
Device symbols require additional memory-attribute detection. Carrying attributes in the event avoids a synthetic query flag.
Fixes internal issue.
How?
Device-symbol events use CUDA-managed type, unknown sys_dev, and zero flags; other allocations are marked registerable.
