+Subject: blkdev_report_zones_ioctl(): Use vmalloc() to allocate large buffers
+
+From: Bart Van Assche <bart.vanassche@wdc.com>
+
+commit 327ea4adcfa37194739f1ec7c70568944d292281 upstream.
+
+Avoid that complaints similar to the following appear in the kernel log
+if the number of zones is sufficiently large:
+
+  fio: page allocation failure: order:9, mode:0x140c0c0(GFP_KERNEL|__GFP_COMP|__GFP_ZERO), nodemask=(null)
+  Call Trace:
+  dump_stack+0x63/0x88
+  warn_alloc+0xf5/0x190
+  __alloc_pages_slowpath+0x8f0/0xb0d
+  __alloc_pages_nodemask+0x242/0x260
+  alloc_pages_current+0x6a/0xb0
+  kmalloc_order+0x18/0x50
+  kmalloc_order_trace+0x26/0xb0
+  __kmalloc+0x20e/0x220
+  blkdev_report_zones_ioctl+0xa5/0x1a0
+  blkdev_ioctl+0x1ba/0x930
+  block_ioctl+0x41/0x50
+  do_vfs_ioctl+0xaa/0x610
+  SyS_ioctl+0x79/0x90
