+Subject: btrfs: fix kvcalloc() arguments order in btrfs_ioctl_send()
+
+From: Dmitry Antipov <dmantipov@yandex.ru>
+
+commit 6ff09b6b8c2fb6b3edda4ffaa173153a40653067 upstream.
+
+When compiling with gcc version 14.0.0 20231220 (experimental)
+and W=1, I've noticed the following warning:
+
+fs/btrfs/send.c: In function 'btrfs_ioctl_send':
+fs/btrfs/send.c:8208:44: warning: 'kvcalloc' sizes specified with 'sizeof'
+in the earlier argument and not in the later argument [-Wcalloc-transposed-args]
+ 8208 |         sctx->clone_roots = kvcalloc(sizeof(*sctx->clone_roots),
+      |                                            ^
+
+Since 'n' and 'size' arguments of 'kvcalloc()' are multiplied to
+calculate the final size, their actual order doesn't affect the result
+and so this is not a bug. But it's still worth to fix it.
