I'm not sure what I should be googling or if FUSE does this (I suspect not). I'd like to create a virtual block device for which all forms of access, for example reads and writes, go directly to my app
I know I can have a file be used as a block device by doing
dd if=/dev/zero of=~/test count=100k then create a loopback to it using
losetup /dev/loop0 ~/test. But I would like accesses going directly to my app instead of to a file. I hope this question is fairly clear.
