Juergen Gross 2ee681584b xen/gntdev: remove struct gntdev_copy_batch from stack ... [ Upstream commit 70045cf659 ] When compiling the kernel with LLVM, the following warning was issued: drivers/xen/gntdev.c:991: warning: stack frame size (1160) exceeds limit (1024) in function 'gntdev_ioctl' The main reason is struct gntdev_copy_batch which is located on the stack and has a size of nearly 1kb. For performance reasons it shouldn't by just dynamically allocated instead, so allocate a new instance when needed and instead of freeing it put it into a list of free structs anchored in struct gntdev_priv.
