Fine. Why not just putting this into a userland filesystem ?

Does it really hurt so bad, compared with all actual AV stuff ?
It has to go to userland anyway, in case you don't intend to
put the scanner into the kernel ;-o

if you have to scan every file then you are right, the userland overhead would be swamped by the scanner overhead. but much of the time you will be accessing files that are already scanned or that you aren't going to scan, but you would still be paying the userland penalty for the filesystem.

2. Networked file systems

What's the problem ?
(btw: 9P already *IS* an network filesystem ;-P)

3. Ioctls

Ah, just forgot a while that this crap still exists ;-o

BUT: do the affected dirs have to contain devices ?
Is there any point for pulling /dev through the AV scanner ?
