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
