David Chinner 45c3414112 [XFS] Apply transaction delta counts atomically to incore counters ... With the per-cpu superblock counters, batch updates are no longer atomic across the entire batch of changes. This is not an issue if each individual change in the batch is applied atomically. Unfortunately, free block count changes are not applied atomically, and they are applied in a manner guaranteed to cause problems. Essentially, the free block count reservation that the transaction took initially is returned to the in core counters before a second delta takes away what is used. because these two operations are not atomic, we can race with another thread that can use the returned transaction reservation before the transaction takes the space away again and we can then get ENOSPC being reported in a spot where we don't have an ENOSPC condition, nor should we ever see one there. Fix it up by rolling the two deltas into the one so it can be applied safely (i.e. atomically) to the incore counters.
