Currently if our iov that we are trying to write is greater than 1024 our write will fail with error "INVALID ARGUMENT". This is because pwritev() system call takes a max input size of IOV_MAX (which is device dependant). With our increased cache size of 1mb or maybe even more (or if user configures batch size to be large), our write size could be greater than IOV_MAX, and will fail with an unhelpful error. We should chunk these writes to ensure they succeed. Bug: 322279333 Test: cow_api_test + manual testing with large iov write sizes Change-Id: Ia1fb53cbfc743cfcdfc7256ff9df075ad0c2dd38 |
