// PidMountInfo collects the mounts for a specific process ID. If the process
// ID is unknown, it is better to use `GetMounts` which will inspect
// "/proc/self/mountinfo" instead.
// PidMountInfo retrieves the list of mounts from a given process' mount
// namespace. Unless there is a need to get mounts from a mount namespace
// different from that of a calling process, use GetMounts.
//
// This function is Linux-specific.
//

// opened /proc/<pid>/mountinfo as an argument instead.
