lookup_one_len_unlocked – filesystem helper to lookup single pathname component
Synopsis
struct dentry *lookup_one_len_unlocked(const char *name, struct dentry *base, int len);Arguments
name
-
- pathname component to lookup
base
- base directory to lookup from
len
- maximum length len should be interpreted to
Description
Note that this routine is purely a helper for filesystem usage and should not be called by generic code.
Unlike lookup_one_len, it should be called without the parent i_mutex held, and will take the i_mutex itself if necessary.
