: Added new flag. (_glibtop_get_fsusage_read_write): Changed prototype.

	* 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.

	(ignore_mount_entry): Added "usbfs" to ignored FS.

	(glibtop_get_mountlist_s): Updated.
