So, where is here hip->subfolders = 0; /* I am here */? Sorry, maybe I missed some email.
1/2 patch do not show more detail about 'hip->subfolders ', you can
apply the patchset to baseline and use '--unified' option to 'git show'
more detail:
```shell
git am '1/2 of the patchset' # to baseline
git show 'commit of 1/2 patch' --unified=16 # specify 16 lines of
context instead of the default 3 lines
```
then you can see more detail as follows:
```shell
...
-struct inode *hfsplus_new_inode(struct super_block *sb, struct inode *dir,
- umode_t mode)
+void hfsplus_init_inode(struct hfsplus_inode_info *hip)
{

- struct inode *inode = new_inode(sb);
- struct hfsplus_inode_info *hip;
-
- if (!inode)
- return NULL;
-
- inode->i_ino = sbi->next_cnid++;
- inode_init_owner(&init_user_ns, inode, dir, mode);
- set_nlink(inode, 1);
- inode->i_mtime = inode->i_atime = inode->i_ctime =
