Public bug reported:
commit 11d83360452ea2a95e699da01f8e1bcc4676a5de (mm, mempool: do not
allow atomic resizing) in Linux 4.1 changed the function prototype for
mempool_resize() by dropping the memory allocation flags parameter.
Add this code to request.c:
+#if LINUX_VERSION_CODE >= KERNEL_VERSION(4, 1, 0)
+ err = mempool_resize(bufs, target);
+#else
err = mempool_resize(bufs, target, GFP_KERNEL);
+#endif
Without this code the DKMS package will not build against the Wily LTS
backport kernel.
