Driver porting: Zero-copy user-space accessDriver porting: Zero-copy user-space accessPosted Mar 3, 2004 7:55 UTC (Wed) by bhepple (guest, #2581)Parent article: Driver porting: Zero-copy user-space access Hmmm, a quick recursive grep through the 2.6.3 driver source and include files showed exactly 0 users of set_page_dirty_lock() and 1 user of put_page() (in drivers/char/agp/generic.c) There _is_ a Am I missing something or should we be using page_cache_release instead of put_page and is it (and set_page_dirty_lock) _really_ needed after all - I can hardly believe all those drivers are causing "data corruption and grumpy users"...
