+    ioctl.h: add missing kernel compatibility header for BUILD_ASSERT
+    
+    Header breakage noticed by cynede. Reproducible as:
+    
+        $ gcc -c /usr/include/btrfs/ioctl.h -o /tmp/a.o
+            /usr/include/btrfs/ioctl.h:42:14: error: expected declaration specifiers or '...' before 'sizeof'
+         BUILD_ASSERT(sizeof(struct btrfs_ioctl_vol_args) == 4096);
+                      ^~~~~~
+    
+    Basically gcc tries to say us BUILD_ASSERT is not visible.
+    
+    BUILD_ASSERT lives in kerncompat.h which this change adds.
