C++ (Cpp) vfs_get_link Examples

Example #1

File: inode.c Project: mkrufky/linux

static const char *ovl_get_link(struct dentry *dentry,
				struct inode *inode,
				struct delayed_call *done)
{
	const struct cred *old_cred;
	const char *p;

	if (!dentry)
		return ERR_PTR(-ECHILD);

	old_cred = ovl_override_creds(dentry->d_sb);
	p = vfs_get_link(ovl_dentry_real(dentry), done);
	revert_creds(old_cred);
	return p;
}

Example #2

static char *ecryptfs_readlink_lower(struct dentry *dentry, size_t *bufsiz)
{
	DEFINE_DELAYED_CALL(done);
	struct dentry *lower_dentry = ecryptfs_dentry_to_lower(dentry);
	const char *link;
	char *buf;
	int rc;

	link = vfs_get_link(lower_dentry, &done);
	if (IS_ERR(link))
		return ERR_CAST(link);

	rc = ecryptfs_decode_and_decrypt_filename(&buf, bufsiz, dentry->d_sb,
						  link, strlen(link));
	do_delayed_call(&done);
	if (rc)
		return ERR_PTR(rc);

	return buf;
