The patch is good, however, there are several calls to find_
lock_delalloc_range in btrfs tests so you'd need to fix those
invocations, otherwise compilation of the in-kernel test suite will fails.
fs/btrfs/tests/extent-io-tests.c: found = find_lock_delalloc_range(inode,
&tmp, locked_page, &start,
fs/btrfs/tests/extent-io-tests.c: found = find_lock_delalloc_range(inode,
&tmp, locked_page, &start,
fs/btrfs/tests/extent-io-tests.c: found = find_lock_delalloc_range(inode,
&tmp, locked_page, &start,
fs/btrfs/tests/extent-io-tests.c: found = find_lock_delalloc_range(inode,
&tmp, locked_page, &start,
fs/btrfs/tests/extent-io-tests.c: found = find_lock_delalloc_range(inode,
&tmp, locked_page, &start,
