This patch fixes a bug in iscsit_allocate_iovecs() where iov_count was incorrectly calculated using min(1UL, data_length / PAGE_SIZE) instead of max(1UL, data_length / PAGE_SIZE), that ends up triggering an OOPs for large block I/O when the SGL <-> iovec mapping exceeds the bogus iov_count allocation size. This is a regression introduced during the iscsi-target conversion back to using core memory allocation here: commit bfb79eac Author: Andy Grover <agrover@redhat.com> Date: Tue Apr 3 15:51:29 2012 -0700 target/iscsi: Go back to core allocating data buffer for cmd Cc: Andy Grover <agrover@redhat.com> Signed-off-by:
