Subject: [PATCH v2 5/7] affs: stop using lock_super

From: Artem Bityutskiy <artem.bityutskiy@...ux.intel.com>

The VFS's 'lock_super()' and 'unlock_super()' calls are deprecated and unwanted
and just wait for a brave knight who'd kill them. This patch makes AFFS stop
using them and use the buffer-head's own lock instead.
