find_inode_number - check for dentry with name
ino_t find_inode_number (struct dentry * dir, struct qstr * name);
dir directory to check
name Name to find.
Check whether a dentry already exists for the given name, and return
the inode number if it has an inode. Otherwise 0 is returned.
This routine is used to post-process directory listings for filesystems
using synthetic inode numbers, and is necessary to keep getcwd working.
