lookup_hash — lookup single pathname component on already hashed name
struct dentry * lookup_hash ( | const 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_unlocked
instead, unless you really know what you are
doing.
Do not hold i_mutex; this helper takes i_mutex if necessary.
