[Devel] [RFC][PATCH 28/36] read_write.c | 1 +: Add checkpoint file operations

[Matt Helsley]

Add the checkpoint operation for generic, read-only files. At present,
 some/all files of the following filesystems use this generic definition:


	freevxfs, romfs, efs, cramfs, isofs, squashfs, befs

This generic filesystem operation definition includes a seek operation
and is thus restartable given the generic checkpoint operation.
