Subject: unionfs: update unionfs fork to align with mainline
Date: Thu, 16 Aug 2012 21:25:01 +0800

mainline commit 0145acc [vfs: uninline full_name_hash] changes the
interface to full_name_hash, so unionfs fork must be updated.
Otherwise unionfs might have the odd behavior that newly created
directories/files in unionfs won't show up in underlying fs properly.

This also implies that 0145acc fixes the corner issue/regression that
introduced by mainline commit bfcfaa7 [vfs: use 'unsigned long'
accesses for dcache name comparison and hashing] and e419b4c [vfs:
make word-at-a-time accesses handle a non-existing page], that newly
adopted fast hash function might have hash collision issue on x86.
