Merge tag 'upstream-3.19-rc1' of git://git.infradead.org/linux-ubifs
Pull UBI/UBIFS updates from Artem Bityutskiy:
"This includes the following UBI/UBIFS changes:
- UBI debug messages now include the UBI device number. This change
is responsible for the big diffstat since it touched every
debugging print statement.
- An Xattr bug-fix which fixes SELinux support
- Several error path fixes in UBI/UBIFS"
* tag 'upstream-3.19-rc1' of git://git.infradead.org/linux-ubifs:
UBI: Fix invalid vfree()
UBI: Fix double free after do_sync_erase()
UBIFS: fix a couple bugs in UBIFS xattr length calculation
UBI: vtbl: Use ubi_eba_atomic_leb_change()
UBI: Extend UBI layer debug/messaging capabilities
UBIFS: fix budget leak in error path
