Type:
Parameter:Nothing

100 | retval = PTR_ERR(kernel_type) |
101 | If IS_ERR(kernel_type) Then Go to out |
104 | kernel_dev = copy_mount_string(dev_name) |
105 | retval = PTR_ERR(kernel_dev) |
106 | If IS_ERR(kernel_dev) Then Go to out1 |
109 | options = copy_mount_options(data) |
114 | If kernel_type && options Then |
115 | If Not strcmp(kernel_type, NFS4_NAME) Then |
117 | If do_nfs4_super_data_conv(options) Then Go to out3 |
122 | retval = Flags is a 32-bit value that allows up to 31 non-fs dependent flags to* be given to the mount() call (ie: read-only, no-dev, no-suid etc) |
