Merge tag 'upstream-3.16-rc1-v2' of git://git.infradead.org/linux-ubifs
Pull UBIFS updates from Artem Bityutskiy: "This contains several UBIFS fixes. One of them fixes a race condition between the mmap page fault path and fsync. Another just removes a bogus assertion from the UBIFS memory shrinker. UBIFS also started honoring the MS_SILENT mount flag, so now it won't print many I/O errors when user-space just tries to probe for the FS. Rest of the changes are rather minor UBI/UBIFS fixes, improvements, and clean-ups" * tag 'upstream-3.16-rc1-v2' of git://git.infradead.org/linux-ubifs: UBIFS: Add an assertion for clean_zn_cnt UBIFS: respect MS_SILENT mount flag UBIFS: Remove incorrect assertion in shrink_tnc() UBIFS: fix debugging check UBIFS: add missing ui pointer in debugging code UBI: block: Fix error path on alloc_workqueue failure UBIFS: Fix dump messages in ubifs_dump_lprops UBI: fix rb_tree node comparison in add_map UBIFS: Remove unused variables in ubifs_budget_space UBI: weaken the 'exclusive' constraint when opening volumes to rename UBIFS: fix an mmap and fsync race condition
