Each of these operations is detailed later in this page. Further flags may be specified in mountflags to modify the behavior of mount(), as described below..
The filesystemtype and data arguments are ignored.
The remaining bits (other than MS_REC, described below) in the mountflags argument are also ignored. .
The only other flags that can be specified while changing the propagation type are MS_REC (described below) and MS_SILENT (which is ignored).
The source, filesystemtype, and data arguments are ignored.
The meanings of the propagation type flags are as follows:).
The remaining bits in the mountflags argument are ignored, as are the filesystemtype and data arguments.
The filesystemtype and data arguments are employed, and further bits may be specified in mountflags to modify the behavior of the.

The parent of a new mount point is defined when the mount point is created. In the usual case, the parent of a new mount is the mount point mount points can be discovered via the /proc/[pid]/mountinfo file (see below).
