FS_Entry reason codes:
0 - NoOp - Just return.
1 - Get device name
r0 - 1 (Reason code)
r1 - FS number.
r2 -> Buffer.
r3 -> device name / id.
Exit:
r0 - length of name
r1 - preserved.
r2 - preserved.
r3 - preserved.
2 - Get free space for device.

[r2] - Total size of device.

Z set if r2 & r6 result in a file on the device pointed to by r3.
This call can simply return with Z set if the filing system is a FAST
filing system (E.G. RAMFS).
The FreeSpace module provides two SWIs:
Free_Register
Entry:
r0 - Filing system number
r1 - Address of routine to call to get free space info (see below)
r1 - r12 on entry to the above routine.
Exit:
Registers preserved.
This must be called in order for the free space module to provide an interactive free space display for a filing system (it is done automatically by the free space module for the following filing systems: ADFS RAMFS NETFS NFS SCSIFS).
Free_Deregister
r0 - Filing system number.
This removes the filing system from the list of known filing systems.
FS_Entry reason codes: (On entry to routine pointed to by r1 in above SWI)
0 - NoOp - Just return.
1 - Get device name
r0 - 1 (Reason code)
r1 - FS number.
r2 -> Buffer.
r3 -> device name / id.

or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with

5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

8. Limitation of Liability. In no event and under no legal theory,

liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
