History
Andy Grover 355eac79d2 Retry if transaction cannot alloc for fallocate or write 
Add a new distinguishable return value (ENOBUFS) from allocator for if
the transaction cannot alloc space. This doesn't mean the filesystem is
full -- opening a new transaction may result in forward progress.

Alter fallocate and get_blocks code to check for this err val and retry
with a new transaction. Handling actual ENOSPC can still happen, of
course.

Add counter called "alloc_trans_retry" and increment it from both spots.
