Subject: USB mass storage backport status?

What's the real status of the mass storage backport to 2.2.18?
Some people report it can corrupt your data, another that it
rebooted his computer while doing a large trasnfer, and so on.

If it's not good, shouldn't it be removed or labeled
DANGEROUS? BTW, where can I see a list of what's backported
and working without major problems?

Depending on the type of device you have and how you use it, it can either:
(1) Work properly
(2) Corrupt your data
(3) Crash the driver
(4) Crash your system

It's allready labeled EXPERIMENTAL. Perhaps it should be labeled
DANGEROUS, also, but how many labels can you put on things to warn people
off?

The reboot was about Iomega's Zip Drive under 2.2.18pre21:

Hmm, where? I don't see an (EXPERIMENTAL) in
Documentation/Configure.help:

USB Mass Storage support
CONFIG_USB_STORAGE
Say Y here if you want to connect USB mass storage devices to your
computer's USB port.

This code is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called usb-storage.o. If you want to compile it
as a module, say M here and read Documentation/modules.txt.

USB Mass Storage verbose debug
CONFIG_USB_STORAGE_DEBUG
Say Y here in order to have the USB Mass Storage code generate
verbose debugging messages.

Maybe it's only enabled when you set CONFIG_EXPERIMENTAL? I don't know, because I enabled
it to just set CONFIG_FB.

AAAHHHHHHHHHH!

Okay, this must have changed somewhat recently. When last I spoke to Alan
Cox (the maintainer of the 2.2.x code), I told him (and he agreed) that
this code should be marked EXPERIMENTAL. If it's not marked thus in
2.2.18pre21, then it's an error and should be corrected ASAP.

It is marked experimental, but the help text is from 2.4test and doesnt
say that. The experimental option is needed and the question asked does
say (EXPERIMENTAL)
