Subject: [PATCH v2 2/2] vfs: clean up d_backing_inode() function
Date:   Wed, 19 Apr 2023 10:47:04 +0000
Message-Id: <20230419104704.243950-1-haifeng.xu@shopee.com>

d_backing_inode() does the same thing with d_inode(), so using
d_inode() to get the inode of dentry instead of d_backing_inode().

Signed-off-by: Haifeng Xu <haifeng.xu@shopee.com>
Suggested-by: Miklos Szeredi <mszeredi@redhat.com>
---
v2:
- replace d_backing_inode() with d_inode()
- remove d_backing_inode() function
- fix code style problems in security_inode_rename()
- improve patch description
