journaling file systems

[Newsmail <newsmail@satimex.tvnet.hu>]

thx jaari for yar answer to my previous mail.

Device backed loop device can be used with journaling 
file
systems as device backed loops guarantee that writes reach disk platters 
in
order required by journaling file system (write caching must be disabled 
on
the disk drive, of course).
that is what I read in the readme of loop-AES. I presume device backed loop 
device means that the entire device or partition is on the loop device, and 
it does not reside in a file. what's up with this write caching thingie. I 
cant make a reiserfs filesystem on an encrypted device if I dont disable 
write caching? what will be the effect if I dont disable it?

other question: if I remember I read something that there are ways to 
compile loop aes to the kernel. is there a way to compile the new 
twofish/blowfish/serpent modules to the kernel as well?
regards,
greg
