New Revision: 1604

Modified:
   trunk/virtualization/unionfuse/trunk/fusioniso/src/fs.c

Log:
Remark from Renzo Davoli :
"the function fs_real_read returns size instead of v_count in two
points, in this way all the files inherited from the 'union' part
never receive the end of file! (a cp or a cat never terminates!)."

It seems we should return the real size read (like described from
into the man page) instead of the number of bytes requested.
