Attached is a small patch that moves the "line_count" upper limit calculation outside the while loop in NVAccelUploadM2MF and NVAccelDownloadM2MF. Benefits are (marginally) faster loops (less instructions, less branch-misses) and slightly cleaner code (imho). -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
