thorpej d3f54e81dd Fix the following pathological scanario: ... * User allocates ZFOD region, but does not actually touch the buffer to fault in the pages. * In a loop, user writes this buffer to a network socket, triggering sosend_loan(). * uvm_loan() calls uvm_loanzero() once for each page in the loaned region (since the pages have not yet faulted in). This causes a page to be allocated and zero'd. The result is the kernel spends a lot of time allocating and zero'ing pages. This fixes creates a special object which owns a single zero'd page. This single zero'd page is used to satisfy all loans of non-resident ZFOD mappings. Thanks to Allen Briggs for discovering the problem and for providing an initial patch.		2003-03-04 06:18:54 +00:00
