The issue occurs when spvadwl, a hash data structure, is uninitialized, and an EVICT FSD request is received from the SEP driver.
tmm cores
The system expects the spvadwl hash to be initialized before handling an EVICT FSD request. If this assumption is incorrect, operations dependent on the hash fail due to its uninitialized state.
N/A
A NULL check has been added to the `spvadwl_search` function to confirm the spvadwl hash is properly initialized before processing. If the hash is uninitialized, the system will ignore the 'EVICT FSD' request, ensuring proper operation and preventing errors.
