ore: FIX breakage when MISC_FILESYSTEMS is not set As Reported by Randy Dunlap When MISC_FILESYSTEMS is not enabled and NFS4.1 is: fs/built-in.o: In function `objio_alloc_io_state': objio_osd.c:(.text+0xcb525): undefined reference to `ore_get_rw_state' fs/built-in.o: In function `_write_done': objio_osd.c:(.text+0xcb58d): undefined reference to `ore_check_io' fs/built-in.o: In function `_read_done': ... When MISC_FILESYSTEMS, which is more of a GUI thing then anything else, is not selected. exofs/Kconfig is never examined during Kconfig, and it can not do it's magic stuff to automatically select everything needed. We must split exofs/Kconfig in two. The ore one is always included. And the exofs one is left in it's old place in the menu.
