From: Leon Romanovsky <leonro@xxxxxxxxxx>
The simple_dname() is declared in internal header file but the
declaration is missing in d_path.c.
The compilation with W=1 generates the following GCC warning.
fs/d_path.c:311:7: warning: no previous prototype for 'simple_dname' [-Wmissing-prototypes]
311 | char *simple_dname(struct dentry *dentry, char *buffer, int buflen)
| ^~~~~~~~~~~~
Fixes: 7e5f7bb08b8c ("unexport simple_dname()")
