fs/Kconfig: move ext2, ext3, ext4, JBD, JBD2 out
Use fs/*/Kconfig more, which is good because everything related to one filesystem is in one place and fs/Kconfig is quite fat. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

+config JBD
+ tristate
+ help
+ This is a generic journalling layer for block devices. It is
+ currently used by the ext3 file system, but it could also be
+ used to add journal support to other file systems or block
+ devices such as RAID or LVM.
+ If you are using the ext3 file system, you need to say Y here.
+ If you are not using ext3 then you will probably want to say N.
+ To compile this device as a module, choose M here: the module will be
+ called jbd. If you are compiling ext3 into the kernel, you
+ cannot compile this code as a module.
+config JBD_DEBUG
+ bool "JBD (ext3) debugging support"
+ depends on JBD && DEBUG_FS
+ help
+ If you are using the ext3 journaled file system (or potentially any
+ other file system/device using JBD), this option allows you to
+ enable debugging output while the system is running, in order to
+ help track down any problems you are having. By default the
+ debugging output will be turned off.
+ If you select Y here, then you will be able to turn on debugging
+ with "echo N > /sys/kernel/debug/jbd/jbd-debug", where N is a
+ number between 1 and 5, the higher the number, the more debugging
+ output is generated. To turn debugging off again, do
+ "echo 0 > /sys/kernel/debug/jbd/jbd-debug".
