i'm trying to write a simple file-system module
and stuck for a while now

the question is
1. How to mount it ? , since the device is needed
some of the tutorial using mount -t none /dev/ " mount_point "
but the error is "the special device none is not exist"

so then , i ve thinkif of another ways ,

creating image , mounting to loop
and mount the loop with my custom fs

but ,since the image must be format to specific partition type before mounting

ie. if mount non-ext3 with mount -t ext3 , error return

so the problem 2 is

2. have i need to write my custom fs utiities too? (like mke2fs,)

ps. According to debug message
my module compile, build , and register_filesystem successfully

No one has commented on your question for a day now, so I will jump and suggest that a simpler method may be to use fuse (Filesystem in Userspace). Fuse is a kernel module that exports the kernel filesystem API to your own userspace application. This is a useful method of exporting data from an application such that other applications can access it using only filesystem methods (open-read-write-close).
Does your requirement include access to an actual mass storage media that is not presently supported?
