The commit 322ea0bb "mtd: switch ubi_open_volume_path() to vfs_stat()"
breaks mounting ubifs volumes for me.
On kernel 4.7-rc3 I am getting the following error when trying to mount
an ubifs volume. This volume in on a ubi file system which exports it as
a mtd partition.
root@lede:/# mkdir /tmp/test
root@lede:/# mount -t ubifs /dev/ubi0_10 /tmp/test/
[ 178.782184] UBIFS error (pid: 955): cannot open "/dev/ubi0_10", error
-22mount: mounting /dev/ubi0_10 on /tmp/test/ failed: Invalid argument
root@lede:/#
In the function ubi_open_volume_path() the call to vfs_stat() returns
-EFAULT.
After I reverted commit 322ea0bb it works again.

Fixes for this are already in Linus' tree and will be part of -rc4. :-)
