Merge tag 'upstream-3.5-rc2' of git://git.infradead.org/linux-ubifs
Pull UBI/UBIFS fixes from Artem Bityutskiy:
"Fix UBI and UBIFS - they refuse to work without debugfs. This was
broken by the 3.5-rc1 UBI/UBIFS changes when we removed the debugging
Kconfig switches.
Also, correct locking in 'ubi_wl_flush()' - it was extended to support
flushing a specific LEB in 3.5-rc1, and the locking was sub-optimal."
* tag 'upstream-3.5-rc2' of git://git.infradead.org/linux-ubifs:
UBI: correct ubi_wl_flush locking
UBIFS: fix debugfs-less systems support
UBI: fix debugfs-less systems support
