lookup_hash — lookup single pathname component on already hashed name
struct dentry * lookup_hash ( | struct qstr * name, |
struct dentry * base); |
The name must have been verified and hashed (see lookup_one_len). Using
this after just full_name_hash is unsafe.
This function also doesn't check for search permission on base directory.
Use lookup_one_len instead, unless you really know what you are
doing.
Do not hold i_mutex; this helper takes i_mutex if necessary.
