Hi,

here is the second bunch of UBIFS updates we would like to send to
Linus for 2.6.27 inclusion. The updates contain the following:

Adrian Hunter (2):
UBIFS: always read hashed-key nodes under TNC mutex
UBIFS: allow for racing between GC and TNC

Artem Bityutskiy (10):
UBIFS: fix zero-length truncations
UBIFS: do not update min_idx_lebs in stafs
UBIFS: push empty flash hack down
UBIFS: remove incorrect index space check
UBIFS: improve statfs reporting
UBIFS: fix assertion
UBIFS: add forgotten gc_idx_lebs component
UBIFS: introduce LEB overhead
UBIFS: improve statfs reporting even more
UBIFS: fill f_fsid

These patches are pure fixes:
UBIFS: fix zero-length truncations
UBIFS: always read hashed-key nodes under TNC mutex
UBIFS: allow for racing between GC and TNC
UBIFS: fix assertion
UBIFS: add forgotten gc_idx_lebs component
UBIFS: remove incorrect index space check

These patches partially fix the problem reported in the MTD ML:
http://lists.infradead.org/pipermail/linux-mtd/2008-August/022579.html

UBIFS: do not update min_idx_lebs in stafs
UBIFS: push empty flash hack down
UBIFS: improve statfs reporting
UBIFS: introduce LEB overhead
UBIFS: improve statfs reporting even more

Thus, it should be fine to send them mainline at this late stage.
Unless there are complaints, I'll send a pull request soon.

Thanks.
