Subject: UBIFS: make minimum fanout 3
X-Git-Tag: 2.1b_release~16524^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a5cb562d6977d9d7989c346b7b153cef31ec0228;p=platform%2Fkernel%2Fkernel-mfld-blackbay.git

UBIFS: make minimum fanout 3

UBIFS does not really work correctly when fanout is 2,
because of the way we manage the indexing tree. It may
just become a list and UBIFS screws up.
