lib: kunit_iov_iter: repeatedly call alloc_pages_bulk()

2026-07-24T14:16:00+00:00

[ Upstream commit 9ac9a08e4ac4bc063e56e1aff266c5e8aa5c6c03 ] alloc_pages_bulk() is not guaranteed to return all requested pages in a single call. Call it repeatedly until all pages have been allocated or no more progress is being made.

lib: kunit_iov_iter: fix memory leaks

2026-05-23T11:06:48+00:00

[ Upstream commit 0b49c7d0ae697fcecd7377cb7dda220f7cd096ff ] Use vfree() instead of vunmap() to free the buffer allocated by iov_kunit_create_buffer() because vunmap() does not honour VM_MAP_PUT_PAGES. In order for this to work the page array itself must not be managed by kunit. Remove the folio_put() when destroying a folioq. This is handled by vfree(), now. Pointed out by sashiko.dev on a previous iteration of this series. Tested by running the kunit test 10000 times in a loop.
