Hi all,

After merging the btrfs tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

fs/btrfs/extent-tree.c: In function 'btrfs_alloc_logged_file_extent':
fs/btrfs/extent-tree.c:4425:20: error: passing argument 1 of 'btrfs_pin_extent' from incompatible pointer type [-Werror=incompatible-pointer-types]
 4425 |   btrfs_pin_extent(fs_info, ins->objectid, ins->offset, 1);
      |                    ^~~~~~~
      |                    |
      |                    struct btrfs_fs_info *
fs/btrfs/extent-tree.c:2609:49: note: expected 'struct btrfs_trans_handle *' but argument is of type 'struct btrfs_fs_info *'
 2609 | int btrfs_pin_extent(struct btrfs_trans_handle *trans,
      |                      ~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~

Caused by commit

  4e2c2f96e6a3 ("btrfs: Make btrfs_pin_extent take trans handle")

interacting with commit

  bd727173e443 ("btrfs: handle logged extent failure properly")

from the btrfs-fixes tree.

I have applied the following merge fix patch for today.
