[PATCH] ext3: reservation info cleanup: remove rsv_seqlock
Since now the ei->truncate_sem is guarding the concurrent allocation and
the deallocation, there is no need to use the the rsv_seqlock lock in the
ext3_reserve_window_node, which was there to protect using/allocating
reservation window race between two threads allocating blocks at the same
time.
