If anyone has any objections, please let me know. ------------------ From: Thorsten Blum [ Upstream commit 7e638679883ceff5b6e7b6dcad09c21a105e941f ] Use the size of the buffer element instead of the pointer size to report the number of bytes read. Since data is a u32 pointer and sizeof(data) is 8 bytes on 64-bit systems, using the pointer size reports twice the number of bytes actually read.
