* fsusage.c: (_glibtop_get_fsusage_read_write) : Added new flag.
(_glibtop_get_fsusage_read_write): Changed prototype. Returns TRUE on
success, then _glibtop_get_fsusage_read_write is set.
Added comment to locate Linux code.
* mountlist.c: (read_filesystem_list): Dropped unused need_fs_type parameter.
This is now default.
Fixed possible leak.
