void nfs_fattr_free_names

(

struct nfs_fattr *

fattr

)

nfs_fattr_free_names - free up the NFSv4 owner and group strings : a fully initialised nfs_fattr structure

Definition at line 129 of file idmap.c.

void nfs_fattr_init_names	(	struct nfs_fattr *	fattr,
		struct nfs4_string *	owner_name,
		struct nfs4_string *	group_name
	)

nfs_fattr_init_names - initialise the nfs_fattr owner_name/group_name fields : fully initialised struct nfs_fattr : owner name string cache : group name string cache

Definition at line 77 of file idmap.c.

void nfs_fattr_map_and_free_names	(	struct nfs_server *	server,
		struct nfs_fattr *	fattr
	)

nfs_fattr_map_and_free_names - map owner/group strings into uid/gid and free : pointer to the filesystem nfs_server structure : a fully initialised nfs_fattr structure

This helper maps the cached NFSv4 owner/group strings in fattr into their numeric uid/gid equivalents, and then frees the cached strings.
