 Isn't CONFIG_EXPERIMENTAL enough?

Of course it is - Adrian is however trying to remove CONFIG_EXPERIMENTAL
and reality is getting in his way again

Re: [2.6.24 patch] let EXT4DEV_FS depend on BROKEN

2008-01-02 Thread Alan Cox 
 Stable kernels are mainly meant for usage, not for trying stuff.

You appear to be reinventing history in your attempt to justify removing
CONFIG_EXPERIMENTAL.

 And although I see a point in perhaps shipping some not-yet-perfect 
 device drivers for otherwise unsupported hardware or some
 not-yet-perfect filesystems required for accessing foreign
 (non-Linux) filesystems, I don't see any point in offering a
 WIP Linux-only filesystem in stable kernels.

So that people can use it and test it. Most people don't run -mm or GIT.

 You can only allocate space on typewriters? ;)

A lot of people get confused about -ENOTTY, but it is the return for
attempting to use an ioctl on the wrong type of object, so this appears
to be quite correct.
