Driver porting: Zero-copy user-space accessDriver porting: Zero-copy user-space accessPosted Nov 2, 2005 21:29 UTC (Wed) by rwbowman (guest, #33561)Parent article: Driver porting: Zero-copy user-space access
TRUE or FALSE - if I map and lock a user space buffer using get_user_pages during ioctl, and then allow the ioctl to return, the pages will remnain locked until I release them with page_cache_release.
I've heard (twice now) where folks say they don't remain locked.?
