Hello there, Static analyser cppcheck says: linux-6.14/arch/arm64/lib/crc-t10dif-glue.c:53:33: error: Using pointer to local variable 'buf' that is out of scope. [invalidLifetime] Source code is return crc_t10dif_generic(crc, data, length); but this line data = buf; looks very suspicious. Suggest move local variable buf out to file scope. Regards David Binderman
