[PATCH 0/3] Export UBI map/unmap/is_mapped in userspace

[Corentin Chary]

Hi,
These are three patch to make a usespace program able to use map/unmap 
operation and to query if a LEB is mapped.
We are trying to do an UBI based userspace filesystem (using fuse) and we 
needed these, but it could also be used for testing purpose.
CONFIG_MTD_UBI_DEBUG_USERSPACE_IO is needed to enable theses functions.

Thanks
