If anyone has any objections, please let me know. ------------------ From: Stanley Jhu [ Upstream commit 2e63ac76cc08ea376ba61fef52f7b7849e35024d ] The reply buffer is allocated once per tag and reused. Requests that complete with a positive status do not fill all of it, so user space receives bytes from an earlier request on the same tag. Clear the whole reply buffer on entry to ufs_bsg_request().
