I have installed Linux 3.5 kernel and have compiled e2fsprogs as well. I have my own version of ext3 file system - lets say it is myfs. I have compiled myfs as well. Now I have few questions:How to insert myfs module and where? When I do modprobe myfs (.ko file) it says module not found. When I simply do insmod myfs.ko it works but I am not sure where is it putting the .ko file. Also the displays I have added (on mkdir call) are not showing up (kernel debug level is also set to 8) when I try to create a directory in mounted folder.  Makefile in myfs directory looks like this:KERNEL_TREE     ?= /lib/modules/$(shell uname -r)/buildPWD     := $(shell pwd)obj-m := iext3.oiext3-objs := balloc.o bitmap.o dir.o file.o fsync.o ialloc.o inode.o \           ioctl.o namei.o super.o symlink.o hash.o resize.o ext3_jbd.o \           xattr.o xattr_user.o xattr_trusted.o acl.o xattr_security.o icefs.o \           transaction.o commit.o recovery.o checkpoint.o revoke.o journal.oall:        make -C $(KERNEL_TREE) M=$(PWD) modulesclean:        rm -rf *.o *~ core .depend .*.cmd *.ko *.mod.c .tmp_versions *.markers *.order *.symversand I am compiling myfs from my own directory: /home/myname/soft/myfs.Also, I don't see any ext2/ext3/ext4 directories in /lib/modules/linuxversion/kernel/fs/ -- not sure if this is right or wrong.Mount is working fine. I can see myfs is mounted on /dev/sda3 by doing df -a. When I unmount It says - umount: /home/..../mnt: not mounted and then if I do df -a the file system is unmounted. This is strange as its unmounting but still throwing error. Some Background:Directory where I have everything: /home/softmyfs/  mye2fs/  Linux-3.5/   mnt/Step1: cd Linux-3.5 --> 1) make 2) make modules 3) make modules_install 4) make install 5) rebootStep2: compile myfs (my version of ext3) and insert the myfs kernel module --> cd myfs/ --> make --> insmod myfs.koStep3: compiled mye2fs for mkfsStep4: use mye2fs to create myfilesystem on a device --> mount --> test printk statements put under myfs modules
