Comment (by pulkomandy):
In hrev50664 I added support for trim to our ramdisk device. This makes it
possible to test the BFS code with a different disk driver. (and is also
useful to release the RAM used by the ramdisk when space is free on the
filesystem).
I did that (with a 8MB disk image) and did not manage to corrupt the
filesystem yet. So either the bug is in the SCSI implementation of trim,
or it needs a disk larger than 8MB to start having problems. Anyway, this
makes it possible to test the BFS side of the code without running it on
actual data.
