This is a generator that yields information about mounted filesystems.
@param mounts_file: A file with information about mounted filesystems,
such as C{/proc/mounts}.
@param statvfs_: A function to get file status information.
@param filesystems_whitelist: Optionally, a list of which filesystems to
stat.
@return: A C{dict} with C{device}, C{mount-point}, C{filesystem},
C{total-space} and C{free-space} keys. If the filesystem information
is not available, C{None} is returned. Both C{total-space} and
C{free-space} are in megabytes.

Tries to determine to which of the mounted filesystem C{path} belongs to,
and then returns information about that filesystem or C{None} if it
couldn't be determined.
@param path: The path we want filesystem information about.
@param mounts_file: A file with information about mounted filesystems,
such as C{/proc/mounts}.
@param statvfs_: A function to get file status information.
@param filesystems_whitelist: Optionally, a list of which filesystems to
stat.
@return: A C{dict} with C{device}, C{mount-point}, C{filesystem},
C{total-space} and C{free-space} keys. If the filesystem information
is not available, C{None} is returned. Both C{total-space} and
C{free-space} are in megabytes.

at the corresponding /sys/block/<device>/removable file

Get a device's "removable" file path.
This function figures out the C{/sys/block/<device>/removable} path
associated with the given device. The file at that path contains either
a "0" if the device is not removable, or a "1" if it is.
@param device: File system path of the device.
