Description Deepak Saxena 2007-09-19 17:06:44 UTC 
Most recent kernel where this bug did not occur: Unknown

Hardware Environment: All

Problem Description:

See 

http://lists.infradead.org/pipermail/linux-mtd/2007-June/018682.html

and the continuation of the discussion at

http://lists.infradead.org/pipermail/linux-mtd/2007-July/018922.html

for details. In summary, commit ff268fb8791cf18df536113355d7184007c269d9
removed the MEMSETOOBSEL ioctl() but the MTD tools (nandwrite) still use 
it. MEMGETOOBSEL is still in the kernel, so either this is a kernel bug and MEMGETOOBSEL should be added, or the tool needs to be rewritten to not
use the ioctls and MEMGETOOBSEL needs to be deleted from the kernel.

Filling a bug b/c the email thread died and this is an obvious bug.
